Then David came to Mahanaim. And Absalom passed over Jordan, he and all the men of Israel with him.

Wesley's Notes

17:24 Passed - Not speedily, but when all the men of Israel were gathered together according to Hushai's counsel.

Jamieson-Fausset-Brown Bible Commentary

24. Then David came to Mahanaim-in the high eastern country of Gilead, the seat of Ish-bosheth's government.

Absalom passed over Jordan-It is not said how long an interval elapsed, but there must have been sufficient time to make the intended levy throughout the kingdom.

Matthew Henry's Concise Commentary

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
