15 Then Hushai said to Zadok and Abiathar, the priests, This is the suggestion made by Ahithophel to Absalom and the responsible men of Israel, and this is what I said to them. 16 So now send the news quickly to David, and say, Do not take your night's rest by the way across the river to the waste land, but be certain to go over; or the king and all the people with him will come to destruction. 17 Now Jonathan and Ahimaaz were waiting by En-rogel; and a servant-girl went from time to time and gave them news and they went with the news to King David, for it was not wise for them to let themselves be seen coming into the town. 18 But a boy saw them, and gave word of it to Absalom: so the two of them went away quickly, and came to the house of a man in Bahurim who had a water-hole in his garden, and they went down into it. 19 And a woman put a cover over the hole, and put crushed grain on top of it, and no one had any knowledge of it. 20 And Absalom's servants came to the woman at the house and said, Where are Ahimaaz and Jonathan? And the woman said to them, They have gone from here to the stream. And after searching for them, and seeing nothing of them, they went back to Jerusalem. 21 Then after the servants had gone away, they came up out of the water-hole and went to give King David the news; and they said, Get up and go quickly over the water, for such and such are Ahithophel's designs against you.
22 So David and all the people who were with him went up over Jordan: when dawn came, every one of them had gone over Jordan.

Commentary on 2 Samuel 17:1-21
(Read 2 Samuel 17:1-21)
Here was a wonderful effect of Divine Providence blinding Absalom's mind and influencing his heart, that he could not rest in Ahithophel's counsel, and that he should desire Hushai's advice. But there is no contending with that God who can arm a man against himself, and destroy him by his own mistakes and passions. Ahithophel's former counsel was followed, for God intended to correct David; but his latter counsel was not followed, for God meant not to destroy him. He can overrule all counsels. Whatever wisdom or help any man employs or affords, the success is from God alone, who will not let his people perish.
Commentary on 2 Samuel 17:22-29
(Read 2 Samuel 17:22-29)
Ahithophel hanged himself for vexation that his counsel was not followed. That will break a proud man's heart which will not break a humble man's sleep. He thought himself in danger, concluding, that, because his counsel was not followed, Absalom's cause would fail; and to prevent a possible public execution, he does justice upon himself. Thus the breath is stopped, and the head laid low, from which nothing could be expected but mischief. Absalom chased his father. But observe how God sometimes makes up to his people that comfort from strangers, which they are disappointed of in their own families. Our King needs not our help; but he assures us, that what we do for the least of his brethren, who are sick, poor, and destitute, shall be accepted and recompensed as if done to himself
