15 Then Hushai said to Zadok and Abiathar the priests, "Thus and so did Ahithophel counsel Absalom and the elders of Israel, and thus and so have I counseled. 16 Now therefore send quickly and tell David, 'Do not stay tonight at the fords of the wilderness, but by all means pass over, lest the king and all the people who are with him be swallowed up.'" 17 Now Jonathan and Ahimaaz were waiting at En-rogel. A female servant was to go and tell them, and they were to go and tell King David, for they were not to be seen entering the city. 18 But a young man saw them and told Absalom. So both of them went away quickly and came to the house of a man at Bahurim, who had a well in his courtyard. And they went down into it. 19 And the woman took and spread a covering over the well's mouth and scattered grain on it, and nothing was known of it. 20 When Absalom's servants came to the woman at the house, they said, "Where are Ahimaaz and Jonathan?" And the woman said to them, "They have gone over the brook[1] of water." And when they had sought and could not find them, they returned to Jerusalem. 21 After they had gone, the men came up out of the well, and went and told King David. They said to David, "Arise, and go quickly over the water, for thus and so has Ahithophel counseled against you."
22 Then David arose, and all the people who were with him, and they crossed the Jordan. By daybreak not one was left who had not crossed the 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
