Introduction
The contest between David and Absalom is now hasting towards a crisis. It must be determined by the sword, and preparation is made accordingly in this chapter. I. Absalom calls a council of war, in which Ahithophel urges despatch (Sa2 17:1-4), but Hushai recommends deliberation (Sa2 17:5-13); and Hushai's counsel is agreed to (Sa2 17:14), for vexation at which Ahithophel hangs himself (Sa2 17:23). II. Secret intelligence is sent to David (but with much difficultly) of their proceedings (Sa2 17:15-21). III. David marches to the other side Jordan (Sa2 17:22-24), and there his camp is victualled by some of his friends in that country (Sa2 17:27-29). IV. Absalom and his forces march after him into the land of Gilead on the other side Jordan (Sa2 17:25, Sa2 17:26). There we shall, in the next chapter, find the cause decided by a battle: hitherto, every thing has looked black upon poor David, but now the day of his deliverance begins to dawn.

Introduction
INTRODUCTION TO SECOND SAMUEL 17
This chapter relates the advice Ahithophel gave to march out speedily with a number of men in pursuit of David, which at first seemed agreeable, Sa2 17:1; but Hushai's opinion being asked, and he giving counsel to raise a larger army, which required time, and was taken to, hereby the counsel of Ahithophel was defeated, Sa2 17:5; upon which he hanged himself, Sa2 17:23; these different counsels being communicated by Hushai to the priests, they found means to transmit them to David, with an instruction to him to pass over Jordan immediately; which he did, and pitched in Gilead, and whither he was followed by Absalom, Sa2 17:15; and where he met with a supply of provisions for his army from some eminent persons in and near that place, Sa2 17:27.

And Absalom made Amasa captain of the host instead of Joab,.... Who was along with David:
which Amasa was a man's son whose name was Ithra, an Israelite; he is called Jether the Ishmaelite, Ch1 2:17; either because he was an Ishmaelite by birth, and being proselyted to the Jewish religion, was called an Israelite; or rather he was an Israelite by birth, and having sojourned in the land of Ishmael some time, was called an Ishmaelite, as Uriah the Hittite, and others; and when Amasa is called a "man's son", it means a great man, as Kimchi observes:
that went in to Abigail, the daughter of Nahash, sister to Zeruiah,
Joab's mother: so that Joab and Amasa, the generals of David and Absalom, were own cousins, sisters' children, and David uncle to them both; for Abigail and Zeruiah were David's sisters, Ch1 2:16; children of Jesse, whose name is here called Nahash, having two names, or this was his surname; though others think Nahash is the name of a woman, the wife of Jesse, and that these two sisters had two mothers, but one father; it seems by this expression, "went in to", as if Amasa was not begotten in the conjugal state, but was illegitimate.
