1 Now these are the nations which the LORD left, to prove Israel by them, even as many of Israel as had not known all the wars of Canaan; 2 Only that the generations of the children of Israel might know, to teach them war, at the least such as before knew nothing thereof; 3 Namely, five lords of the Philistines, and all the Canaanites, and the Sidonians, and the Hivites that dwelt in mount Lebanon, from mount Baal-hermon unto the entering in of Hamath. 4 And they were to prove Israel by them, to know whether they would hearken unto the commandments of the LORD, which he commanded their fathers by the hand of Moses. 5 And the children of Israel dwelt among the Canaanites, Hittites, and Amorites, and Perizzites, and Hivites, and Jebusites: 6 And they took their daughters to be their wives, and gave their daughters to their sons, and served their gods. 7 And the children of Israel did evil in the sight of the LORD, and forgat the LORD their God, and served Baalim and the groves. 8 Therefore the anger of the LORD was hot against Israel, and he sold them into the hand of Chushan-rishathaim king of Mesopotamia: and the children of Israel served Chushan-rishathaim eight years. 9 And when the children of Israel cried unto the LORD, the LORD raised up a deliverer to the children of Israel, who delivered them, even Othniel the son of Kenaz, Caleb's younger brother. 10 And the Spirit of the LORD came upon him, and he judged Israel, and went out to war: and the LORD delivered Chushan-rishathaim king of Mesopotamia into his hand; and his hand prevailed against Chushan-rishathaim. 11 And the land had rest forty years. And Othniel the son of Kenaz died. 12 And the children of Israel did evil again in the sight of the LORD: and the LORD strengthened Eglon the king of Moab against Israel, because they had done evil in the sight of the LORD. 13 And he gathered unto him the children of Ammon and Amalek, and went and smote Israel, and possessed the city of palm trees. 14 So the children of Israel served Eglon the king of Moab eighteen years. 15 But when the children of Israel cried unto the LORD, the LORD raised them up a deliverer, Ehud the son of Gera, a Benjamite, a man lefthanded: and by him the children of Israel sent a present unto Eglon the king of Moab. 16 But Ehud made him a dagger which had two edges, of a cubit length; and he did gird it under his raiment upon his right thigh. 17 And he brought the present unto Eglon king of Moab: and Eglon was a very fat man. 18 And when he had made an end to offer the present, he sent away the people that bare the present. 19 But he himself turned again from the quarries that were by Gilgal, and said, I have a secret errand unto thee, O king: who said, Keep silence. And all that stood by him went out from him. 20 And Ehud came unto him; and he was sitting in a summer parlour, which he had for himself alone. And Ehud said, I have a message from God unto thee. And he arose out of his seat. 21 And Ehud put forth his left hand, and took the dagger from his right thigh, and thrust it into his belly: 22 And the haft also went in after the blade; and the fat closed upon the blade, so that he could not draw the dagger out of his belly; and the dirt came out. 23 Then Ehud went forth through the porch, and shut the doors of the parlour upon him, and locked them. 24 When he was gone out, his servants came; and when they saw that, behold, the doors of the parlour were locked, they said, Surely he covereth his feet in his summer chamber. 25 And they tarried till they were ashamed: and, behold, he opened not the doors of the parlour; therefore they took a key, and opened them: and, behold, their lord was fallen down dead on the earth. 26 And Ehud escaped while they tarried, and passed beyond the quarries, and escaped unto Seirath. 27 And it came to pass, when he was come, that he blew a trumpet in the mountain of Ephraim, and the children of Israel went down with him from the mount, and he before them. 28 And he said unto them, Follow after me: for the LORD hath delivered your enemies the Moabites into your hand. And they went down after him, and took the fords of Jordan toward Moab, and suffered not a man to pass over. 29 And they slew of Moab at that time about ten thousand men, all lusty, and all men of valour; and there escaped not a man. 30 So Moab was subdued that day under the hand of Israel. And the land had rest fourscore years. 31 And after him was Shamgar the son of Anath, which slew of the Philistines six hundred men with an ox goad: and he also delivered Israel.
[AD 435] John Cassian on Judges 3:1-4
As useful as it is to me that you [the Lord] should leave me for a little while in order to test the steadfastness of my desire, so it is harmful if you let me be abandoned for too long because of my deserts and my sins. For no human strength will be able to endure by its own steadfastness if it is too long abandoned by your help in time of trial. Nor will it be able to give way instantly before the power and wherewithal of the adversary if you yourself, who are aware of human strengths and are the arbiter of our struggles, “do not permit us to be tried beyond our capacity, but with the trial also provide a way out, so that we may be able to endure.”We read something like this as it appears in mystical fashion in the book of Judges with respect to the extermination of the spiritual nations that are opposed to Israel: “These are the nations that the Lord forsook, so that by them he might instruct Israel, so that they might grow accustomed to fighting with their enemies.” And again, a little further on: “The Lord left them so that he might test Israel with them, whether or not they would hear the commandments of the Lord that he had laid down for their forefathers by the hand of Moses.” God did not begrudge Israel their peace or look with malice upon them, but he planned this conflict in the knowledge that it would be beneficial. Thus, constantly oppressed by the onslaught of the nations, they would never feel that they did not need the Lord’s help. Hence they would always meditate on him and cry out to him, and they would neither lapse into sluggish inactivity nor lose their ability to fight and their training in virtue. For frequently security and prosperity have brought low those whom adversities cannot overcome.

[AD 604] Gregory the Dialogist on Judges 3:1-4
Almighty God shows wonderful providence in distributing his blessings. Frequently, by denying lesser gifts to those whom he has favored with great virtues, he offers their souls an opportunity for self-reproach. When they find themselves unable to reach the perfection they aspire to and see themselves struggling in vain for a mastery of virtues not granted them, they are not likely to pride themselves on the gifts they have received. For, when they see that of their own power they are incapable of overcoming small faults and slight imperfections, they begin to realize that their great virtues were not self-acquired. For a similar reason the Lord destroyed the powerful enemies who beset his chosen people on their way to the promised land, but [he] allowed the Philistines and Canaanites to survive, so that, as it is written, “he might try Israel by them.” Sometimes, as I have said, those who have received exceptional graces are the very ones God allows to retain small imperfections so that they may always have obstacles with which to contend. As a result they do not foster pride in their hearts even though they are victorious over powerful enemies, for they realize that the weakest of adversaries still causes them great weariness. It is quite remarkable how one and the same person can be vigorous in virtue and weak with infirmity, and while strongly fortified on one side see himself laid waste on the other. The good, therefore, for which he is striving without success, makes him cherish humbly the gifts God has given him.Why should we be surprised that this is true of people? Heaven itself witnessed the same occurrence, for some of its citizens were lost and some stood firm. Seeing one part fall through pride, the other, the chosen angels, kept their stand more humbly and therefore also more firmly. This loss, then, was beneficial for those citizens of heaven whom it helped to establish more firmly in their eternal condition. The same is true of us individually. A slight loss that safeguards humility can at times be of immense profit to a soul.

[AD 253] Origen of Alexandria on Judges 3:7-8
Now Chusarsaton’s name is translated as “humiliation.” They were delivered, then, to the hands of one who would humiliate them. And it was because they acted wickedly on the heights of the mountains against the Most High that he sent them to their humiliation. But I don’t want you to think that it is only in relation to the ancients that divine providence delivers those who were exalted in wickedness for the purpose of humiliating them and that they may be healed by such a wholesome remedy. Presently as well, almighty God’s healing providence is [not] lacking in relation to his church. Even now, there is a “Chusarsaton king of Mesopotamia” to whom souls are handed over for humiliation and affliction, souls who had moved themselves from despised Christian humility into pride and arrogance. The vice of pride is utterly hateful in the sight of God, for, as Scripture says, “pride is the beginning of departure from God” and, again, “God resists the proud, but gives grace to the humble.”

[AD 1781] Richard Challoner on Judges 3:8
Mesopotamia: In Hebrew Aramnaharim. Syria of the two rivers: so called because it lies between the Euphrates and the Tigris. It is absolutely called Syria, ver. 10.
[AD 253] Origen of Alexandria on Judges 3:9
It calls the savior “Othniel,” which means “the time of God for me.” Through this first Othniel, then, the people were delivered from their humiliating servility and were restored to peace rather than having their longstanding pride and various deeds removed. But because we already said that a certain spiritual identity can be found in King Chusarsaton as one of the adversaries and a prince of the “powers of the air,” it seems to me fitting to say that Othniel likewise, who was raised up to deliver the people, is a member of the “host of heaven” and of the throng of archangels who “are sent to support those who receive the inheritance of salvation.” These angels are saviors, moreover, designated under the form of Othniel or Ehud, for, as we have often shown, we do not fight alone against the powers of the enemy, but good forces and powers are also sent to our aid by the Lord.

[AD 435] John Cassian on Judges 3:9
We frequently find this calling from need in Scripture as well, when we read that on account of their sins, the children of Israel were delivered over by the Lord to their enemies and that, having changed their course because of their domination and savage cruelty, they cried out to the Lord. “And the Lord sent them,” it says, “a deliverer named Ehud, the son of Gera, the son of Jemini, who used either hand as if it were his right hand.” And again it says, “They cried out to the Lord, who raised up a deliverer for them, Othniel, the son of Kenaz, the younger brother of Caleb, and he freed them.” And it said of them in a psalm: “When he killed them, then they sought him, and they turned and at dawn they came to God, and they remembered that God was their helper.” And again: “They cried out to the Lord when they were troubled, and he freed them from their distress.”Of these three kinds [of calling from need], then, although the first two seem to be supported by better beginnings, nonetheless we find that even on the third level [recorded by the psalmist], which seems inferior and lukewarm, there have been people who are perfect and very fervent in spirit, similar to those who have made an excellent beginning in the Lord’s service and have passed the rest of their lives in praiseworthy intensity of spirit. Likewise there are many who have become tepid and have fallen from a higher level and very frequently ended up in tragedy. [Thus], just as it was no drawback to the former that they seem to have been converted not by their own will but by force of necessity, inasmuch as the Lord’s kindness furnished the occasion whereby they might feel compunction, likewise their having been converted in some sublime fashion profited the latter nothing whatsoever, because they did not strive to live out the rest of their days accordingly.

[AD 253] Origen of Alexandria on Judges 3:15-21
Let’s observe how Ehud, whose name means “praise,” discharged his leadership. History teaches us, in its writings about King Eglon, how this most wise Ehud with particular skill and, if I may say, cunning but praiseworthy deception, would kill the tyrant Eglon, whose name means “round” or “circular.” It was necessary, then, to have the quality of judges of our people as was this Ehud, whose name means “praise,” so to cut through all his rolling motion and circuit of evil ways and to destroy the king of the Moabites. But Moabite is translated as “flow” or “effusion.” Who can the ruler or leader of this flowing and dissolute people be seen or understood to be, therefore, other than the word of that philosophy which adjudges pleasure to be the highest good, a philosophy which the word of the gospel, which has been compared to a sword, killed and destroyed? And this prophetic word would become enclosed within their belly and lowest stomach by means of the “ambidextrous” judge’s arguments, to extinguish the Moabites by assertion of the truth, enclosing also every sense of perverse doctrine and dull understanding “which extols itself and rises against the spiritual knowledge of Christ,” so that by acting thus and by doing battle with the word of God, each judge of the church may also become a praising Ehud, about whom the Lord would say, “Well done, good and faithful servant; you have been faithful over a few, so I will set you over many.”

[AD 420] Jerome on Judges 3:15-21
What did you mean by saying, two thousand fall at the side? Naturally, when the right hand is designated and the left is not, the side is named in place of the left hand. It would not be right, certainly, for the just man to have a left hand: “If someone strikes you on the right cheek,” counsels the Lord, “turn to him the other also.” Notice that he did not say, “the left also,” for it is not the left cheek that is offered, but another right cheek. I shall express this very plainly, therefore, by saying that the just man has two right cheeks. The man, Ehud, for example, who is written of in the book of Judges, is said to have two right hands because he was a just man and killed that fat stupid king. “Though two thousand fall at your side, ten thousand at your right hand.” There are very many who lie in wait at our right hand, not so many who plot against our left; [thus], a thousand fall at our side and ten thousand at our right hand. Where there is greater combat, there is, of course, greater victory. Few lie in ambush at our side, but many at our right hand.

[AD 435] John Cassian on Judges 3:15-21
These are the persons, then, who are referred to in holy Scripture as amphoterodexioi—that is, as ambidextrous. Ehud, “who used either hand as if it were his right hand,” is described as such in the book of Judges. We shall also be able to possess this quality in a spiritual way if by a good and correct use we put the things which are considered fortunate and right-handed and the things which are called unfortunate and left-handed on the right side, that whatever befalls may become for us, in the words of the apostle, “the arms of righteousness.” For we see that our inner man consists in two parts or, as I might say, two hands. No holy person can be without what we call the left hand, but perfect virtue is discerned in the fact that by proper use he turns both into a right hand.

[AD 1781] Richard Challoner on Judges 3:20
A word from God: What Aod, who was judge and chief magistrate of Israel, did on this occasion, was by a special inspiration of God: but such things are not to be imitated by private men.
[AD 430] Augustine of Hippo on Judges 3:30
Now, judges were established over them from the time they took over the promised land and before the monarchy began. And even during this era, the children of iniquity, that is, foreign foes, afflicted them, for we read they had now peace, now war. Even so, you can find periods of peace in the age of the judges longer than that of Solomon, who reigned forty years. Specifically, under the judge named Ehud, there were eighty years of peace.
