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 himselfThen David arose, and all the people that were with him, and passed over Jordan,.... Taking the advice of Hushai:

by the morning light there lacked not one of them that was not gone over Jordan; they travelled all night, and before it was morning they had all passed the river in boats, or through the fords, and not one was lost in the passage, nor any deserted, see John 17:12; and now perhaps David penned the forty second and forty third psalms, Psalm 42:1.
