1 And the children of Israel set forward, and pitched in the plains of Moab on this side Jordan by Jericho. 2 And Balak the son of Zippor saw all that Israel had done to the Amorites. 3 And Moab was sore afraid of the people, because they were many: and Moab was distressed because of the children of Israel. 4 And Moab said unto the elders of Midian, Now shall this company lick up all that are round about us, as the ox licketh up the grass of the field. And Balak the son of Zippor was king of the Moabites at that time. 5 He sent messengers therefore unto Balaam the son of Beor to Pethor, which is by the river of the land of the children of his people, to call him, saying, Behold, there is a people come out from Egypt: behold, they cover the face of the earth, and they abide over against me: 6 Come now therefore, I pray thee, curse me this people; for they are too mighty for me: peradventure I shall prevail, that we may smite them, and that I may drive them out of the land: for I wot that he whom thou blessest is blessed, and he whom thou cursest is cursed. 7 And the elders of Moab and the elders of Midian departed with the rewards of divination in their hand; and they came unto Balaam, and spake unto him the words of Balak. 8 And he said unto them, Lodge here this night, and I will bring you word again, as the LORD shall speak unto me: and the princes of Moab abode with Balaam. 9 And God came unto Balaam, and said, What men are these with thee? 10 And Balaam said unto God, Balak the son of Zippor, king of Moab, hath sent unto me, saying, 11 Behold, there is a people come out of Egypt, which covereth the face of the earth: come now, curse me them; peradventure I shall be able to overcome them, and drive them out. 12 And God said unto Balaam, Thou shalt not go with them; thou shalt not curse the people: for they are blessed. 13 And Balaam rose up in the morning, and said unto the princes of Balak, Get you into your land: for the LORD refuseth to give me leave to go with you. 14 And the princes of Moab rose up, and they went unto Balak, and said, Balaam refuseth to come with us. 15 And Balak sent yet again princes, more, and more honourable than they. 16 And they came to Balaam, and said to him, Thus saith Balak the son of Zippor, Let nothing, I pray thee, hinder thee from coming unto me: 17 For I will promote thee unto very great honour, and I will do whatsoever thou sayest unto me: come therefore, I pray thee, curse me this people. 18 And Balaam answered and said unto the servants of Balak, If Balak would give me his house full of silver and gold, I cannot go beyond the word of the LORD my God, to do less or more. 19 Now therefore, I pray you, tarry ye also here this night, that I may know what the LORD will say unto me more. 20 And God came unto Balaam at night, and said unto him, If the men come to call thee, rise up, and go with them; but yet the word which I shall say unto thee, that shalt thou do. 21 And Balaam rose up in the morning, and saddled his ass, and went with the princes of Moab. 22 And God's anger was kindled because he went: and the angel of the LORD stood in the way for an adversary against him. Now he was riding upon his ass, and his two servants were with him. 23 And the ass saw the angel of the LORD standing in the way, and his sword drawn in his hand: and the ass turned aside out of the way, and went into the field: and Balaam smote the ass, to turn her into the way. 24 But the angel of the LORD stood in a path of the vineyards, a wall being on this side, and a wall on that side. 25 And when the ass saw the angel of the LORD, she thrust herself unto the wall, and crushed Balaam's foot against the wall: and he smote her again. 26 And the angel of the LORD went further, and stood in a narrow place, where was no way to turn either to the right hand or to the left. 27 And when the ass saw the angel of the LORD, she fell down under Balaam: and Balaam's anger was kindled, and he smote the ass with a staff. 28 And the LORD opened the mouth of the ass, and she said unto Balaam, What have I done unto thee, that thou hast smitten me these three times? 29 And Balaam said unto the ass, Because thou hast mocked me: I would there were a sword in mine hand, for now would I kill thee. 30 And the ass said unto Balaam, Am not I thine ass, upon which thou hast ridden ever since I was thine unto this day? was I ever wont to do so unto thee? And he said, Nay. 31 Then the LORD opened the eyes of Balaam, and he saw the angel of the LORD standing in the way, and his sword drawn in his hand: and he bowed down his head, and fell flat on his face. 32 And the angel of the LORD said unto him, Wherefore hast thou smitten thine ass these three times? behold, I went out to withstand thee, because thy way is perverse before me: 33 And the ass saw me, and turned from me these three times: unless she had turned from me, surely now also I had slain thee, and saved her alive. 34 And Balaam said unto the angel of the LORD, I have sinned; for I knew not that thou stoodest in the way against me: now therefore, if it displease thee, I will get me back again. 35 And the angel of the LORD said unto Balaam, Go with the men: but only the word that I shall speak unto thee, that thou shalt speak. So Balaam went with the princes of Balak. 36 And when Balak heard that Balaam was come, he went out to meet him unto a city of Moab, which is in the border of Arnon, which is in the utmost coast. 37 And Balak said unto Balaam, Did I not earnestly send unto thee to call thee? wherefore camest thou not unto me? am I not able indeed to promote thee to honour? 38 And Balaam said unto Balak, Lo, I am come unto thee: have I now any power at all to say any thing? the word that God putteth in my mouth, that shall I speak. 39 And Balaam went with Balak, and they came unto Kirjath-huzoth. 40 And Balak offered oxen and sheep, and sent to Balaam, and to the princes that were with him. 41 And it came to pass on the morrow, that Balak took Balaam, and brought him up into the high places of Baal, that thence he might see the utmost part of the people.
[AD 542] Caesarius of Arles on Numbers 22:5
This Balaam was exceedingly famous for his magical art and very powerful with his harmful verses. He did not possess the power or skill of words in blessing but only in cursing, for the demons are invited to curse but not to bless. As he was experienced in such matters, for this reason he was esteemed by all men in the Orient. Indeed, abundant proofs of it had happened before when he had frequently turned back an armed enemy with his curses. Otherwise the king surely would not have presumed that what could not be accomplished by iron and the sword could be done by words. Therefore Balak was sure of it and had frequently tried it, for he put aside all instruments and aids of war and sent ambassadors to him saying, “A people has come here from Egypt, who now cover the face of the earth and are settling down opposite us.”

[AD 397] Ambrose of Milan on Numbers 22:17
Love of money then is an old and ancient vice, which showed itself even at the declaration of the divine law; for a law was given to check it. On account of love of money Balak thought Balaam could be tempted by rewards to curse the people of our fathers. Love of money would have won the day too, had not God bidden him hold back from cursing.

[AD 1781] Richard Challoner on Numbers 22:19
To stay: His desiring them to stay, after he had been fully informed already that it was not God's will he should go, came from the inclination he had to gratify Balac, for the sake of worldly gain. And this perverse disposition God punished by permitting him to go (though not to curse the people as he would willingly have done), and suffering him to fall still deeper and deeper into sin, till he came at last to give that abominable counsel against the people of God, which ended in his own destruction. So sad a thing it is to indulge a passion for money.
[AD 397] Ambrose of Milan on Numbers 22:25
What offense does Balaam commit, except that he said one thing and plotted another? For God seeks out a pure vessel, one not corrupted by impurity and squalor. Balaam was tested, therefore, but he was not found acceptable: “For he was full of lies and guile.” In short, when he first inquired whether he ought to go to that vain people and was stopped, he made excuses. Later, when more important legates were sent and more copious things were promised, he was enticed by the richer gifts—although he should have renounced them—and decided that there should be another consultation, as though God could be affected either by a bribe or by gifts. The response was given as though to a greedy man and not as to one seeking the truth, so that he might be mocked rather than informed. He set out, and an angel met him in a narrow place. He revealed himself to the ass. He did not reveal himself to the seer. He revealed himself to the one; he disgraced the other. Nevertheless, in order that he himself might at some point come to recognition, “he opened his eyes.” He saw and still did not believe the clear oracle. He who should have believed his own eyes responded obscurely and ambiguously.

[AD 604] Gregory the Dialogist on Numbers 22:25
The spirit which is carried out of itself to pride is made to remember the condition to which it is subject, owing to the ills of the flesh which it bears. This was rightly indicated though Balaam (if only he had been willing to follow obediently the voice of God!) in that his journey was retarded. For we see Balaam on the way to attain his purpose, but the beast under him thwarts his intention. The ass, stopped by a command, perceives an angel not seen by the mind of the man. For commonly the flesh, retarded by affliction, manifests to the mind the God whom the mind itself did not see, though it dominates the flesh, owing to the scourgings it receives.

[AD 253] Origen of Alexandria on Numbers 22:28
I marvel at Balaam’s ass and heap blessings on it, because it was worthy not only to see the angel of God but even to have its mouth opened and break into human speech.

[AD 1781] Richard Challoner on Numbers 22:28
Opened the mouth: The angel moved the tongue of the ass, to utter these speeches, to rebuke, by the mouth of a brute beast, the brutal fury and folly of Balaam.
[AD 1781] Richard Challoner on Numbers 22:32
Perverse: Because thy inclinations are wicked in being willing for the sake of gain to curse the people of whom I am the guardian.
