1 Moreover Ahithophel said unto Absalom, Let me now choose out twelve thousand men, and I will arise and pursue after David this night: 2 And I will come upon him while he is weary and weak handed, and will make him afraid: and all the people that are with him shall flee; and I will smite the king only: 3 And I will bring back all the people unto thee: the man whom thou seekest is as if all returned: so all the people shall be in peace. 4 And the saying pleased Absalom well, and all the elders of Israel. 5 Then said Absalom, Call now Hushai the Archite also, and let us hear likewise what he saith. 6 And when Hushai was come to Absalom, Absalom spake unto him, saying, Ahithophel hath spoken after this manner: shall we do after his saying? if not; speak thou. 7 And Hushai said unto Absalom, The counsel that Ahithophel hath given is not good at this time. 8 For, said Hushai, thou knowest thy father and his men, that they be mighty men, and they be chafed in their minds, as a bear robbed of her whelps in the field: and thy father is a man of war, and will not lodge with the people. 9 Behold, he is hid now in some pit, or in some other place: and it will come to pass, when some of them be overthrown at the first, that whosoever heareth it will say, There is a slaughter among the people that follow Absalom. 10 And he also that is valiant, whose heart is as the heart of a lion, shall utterly melt: for all Israel knoweth that thy father is a mighty man, and they which be with him are valiant men. 11 Therefore I counsel that all Israel be generally gathered unto thee, from Dan even to Beer-sheba, as the sand that is by the sea for multitude; and that thou go to battle in thine own person. 12 So shall we come upon him in some place where he shall be found, and we will light upon him as the dew falleth on the ground: and of him and of all the men that are with him there shall not be left so much as one. 13 Moreover, if he be gotten into a city, then shall all Israel bring ropes to that city, and we will draw it into the river, until there be not one small stone found there. 14 And Absalom and all the men of Israel said, The counsel of Hushai the Archite is better than the counsel of Ahithophel. For the LORD had appointed to defeat the good counsel of Ahithophel, to the intent that the LORD might bring evil upon Absalom. 15 Then said Hushai unto Zadok and to Abiathar the priests, Thus and thus did Ahithophel counsel Absalom and the elders of Israel; and thus and thus have I counselled. 16 Now therefore send quickly, and tell David, saying, Lodge not this night in the plains of the wilderness, but speedily pass over; lest the king be swallowed up, and all the people that are with him. 17 Now Jonathan and Ahimaaz stayed by En-rogel; for they might not be seen to come into the city: and a wench went and told them; and they went and told king David. 18 Nevertheless a lad saw them, and told Absalom: but they went both of them away quickly, and came to a man's house in Bahurim, which had a well in his court; whither they went down. 19 And the woman took and spread a covering over the well's mouth, and spread ground corn thereon; and the thing was not known. 20 And when Absalom's servants came to the woman to the house, they said, Where is Ahimaaz and Jonathan? And the woman said unto them, They be gone over the brook of water. And when they had sought and could not find them, they returned to Jerusalem. 21 And it came to pass, after they were departed, that they came up out of the well, and went and told king David, and said unto David, Arise, and pass quickly over the water: for thus hath Ahithophel counselled against you. 22 Then David arose, and all the people that were with him, and they passed over Jordan: by the morning light there lacked not one of them that was not gone over Jordan. 23 And when Ahithophel saw that his counsel was not followed, he saddled his ass, and arose, and gat him home to his house, to his city, and put his household in order, and hanged himself, and died, and was buried in the sepulchre of his father. 24 Then David came to Mahanaim. And Absalom passed over Jordan, he and all the men of Israel with him. 25 And Absalom made Amasa captain of the host instead of Joab: which Amasa was a man's son, whose name was Ithra an Israelite, that went in to Abigail the daughter of Nahash, sister to Zeruiah Joab's mother. 26 So Israel and Absalom pitched in the land of Gilead. 27 And it came to pass, when David was come to Mahanaim, that Shobi the son of Nahash of Rabbah of the children of Ammon, and Machir the son of Ammiel of Lo-debar, and Barzillai the Gileadite of Rogelim, 28 Brought beds, and basons, and earthen vessels, and wheat, and barley, and flour, and parched corn, and beans, and lentiles, and parched pulse, 29 And honey, and butter, and sheep, and cheese of kine, for David, and for the people that were with him, to eat: for they said, The people is hungry, and weary, and thirsty, in the wilderness.
[AD 407] John Chrysostom on 2 Samuel 17:1-4
There is nothing so foreign to a Christian soul as haughtiness. Haughtiness, I say, not boldness nor courage, for these are agreeable. But these are one thing, and that is another; so too humility is one thing, and ignobility, flattery and adulation another. I will now, if you wish, give you examples of all these qualities. For these things which are contraries, seem in some way to be placed close together, as the tares are to the wheat and the thorns to the rose. But while babes might easily be deceived, those who are mature in truth and are skilled in spiritual husbandry know how to separate what is really good from the bad. Let me then lay before you examples of these qualities from the Scriptures. What is flattery and ignobility and adulation? Ziba flattered David out of season and falsely slandered his master. Much more did Ahitophel flatter Absalom. But David was not like this but was humble. For the deceitful are flatterers, as when they say, “O king, live forever.” Again, what flatterers the magicians are.

[AD 430] Augustine of Hippo on 2 Samuel 17:14
Accordingly, as the Scripture says, “And by the command of the Lord the good counsel of Ahithophel was defeated, that the Lord might bring evil upon Absalom.” The counsel of Ahithophel was called “good” because it served his purpose for the time, since it favored Absalom over his father whom he had risen up against in rebellion. And it might well have destroyed him if the Lord had not frustrated Ahithophel’s counsel by influencing the heart of Absalom to reject this counsel and to choose another which was not to his advantage.

[AD 435] John Cassian on 2 Samuel 17:14
For what shall we say about Hushai’s pious deception of Absalom for the sake of King David’s safety which, although formulated with good will by the deceiver and cheater and opposed to the well-being of the questioner, is approved by the text of divine Scripture that says, “By the will of the Lord the useful advice of Ahithophel was undone, so that the Lord might bring evil upon Absalom”? For what was accomplished with a right intention and pious judgment for a good purpose and conceived for the safety and religious victory of a man whose piety was pleasing to God, all by way of deception, could not be blamed.

[AD 379] Basil of Caesarea on 2 Samuel 17:15-16
For in the history, Hushai is mentioned as the chief companion of David and the son of Arachi, but in the psalm, Hushai is the son of Jemini. Neither he nor any other of those appearing in the history was the son of Jemini. Perhaps he was called the son of Jemini for this reason, because he displayed great valor and strength through a mere pretense of friendship, going over, as he pretended, to Absalom, but in reality thwarting the plans of Ahithophel, a very skilled man, well trained in military affairs, who was giving his counsel. “The son of Jemini” is interpreted “the son of the right hand.” By his proposals he prevented the acceptance of the plan of Ahithophel—that no time should intervene in the affairs but that an attack should be made immediately on the father while he was unprepared—“in order that,” as Scripture says, “the Lord might bring all evils upon Absalom.” At all events, he seemed to them to introduce more plausible reasons for postponement and delay, while his real purpose was to give time to David to gather his forces. Because of Hushai’s counsel he was acceptable to Absalom, who said, “The counsel of Hushai the Archite is better than the counsel of Ahithophel.”However, Hushai informed David through the priests Zadok and Abiathar of the decision and bade him not to camp in Araboth in the desert but urged him to cross it. Since, then, he was on the right hand of David through his good advice, he obtained the name from his brave deed. Surely it is because of this that he is called “son of Jemini,” that is, “son of the right hand.” It is a custom of Scripture not only to give those who are more wicked a name from their sin rather than from their fathers but also to call the better sons from the virtue characterizing them.

[AD 435] John Cassian on 2 Samuel 17:19-20
And what shall we say about the deed of the woman who received those who had been sent to King David by the aforementioned Hushai and who hid them in a well, spreading a cover over the mouth of it and making believe that she was drying barley? “They went on,” she said, “after having drunk a little water,” and by this trick she saved them from the hands of their pursuers. Tell me, then, I ask you, what you would have done if a similar situation had arisen for you who now live under the gospel. Would you have chosen to conceal them by a similar lie, saying in the same way, “They went on after having drunk a little water,” thus fulfilling what is commanded, “Do not spare [your help] to save those who are being led to death and to redeem those who are being slain” Or by speaking the truth would you have given over those who were hidden to those who were going to kill them? What, then, of the apostle’s words? “Let no one seek what is [to] his own [benefit] but rather [to] what is another’s.” And, “Love does not seek what is its own but rather what belongs to others.” And what he says about himself, “I do not seek what is beneficial to me but what is beneficial to the many, so that they may be saved.” For if we seek what is ours and wish to hold on obstinately to what is beneficial to us, we shall have to speak the truth even in difficulties of this sort, and we shall become guilty of another’s death. But if we fulfill the apostolic command by placing what is helpful to others ahead of our own well-being, without a doubt the necessity of lying will be imposed upon us.
