How far Abner's deserting the house of Saul, his murder, and the murder of Ish-bosheth, might contribute to the perfecting of the revolution, and the establishing of David as king over all Israel, does not appear; but, it should seem, that happy change followed presently thereupon, which in this chapter we have an account of. Here is, I. David anointed king by all the tribes (Sa2 5:1-5). II. Making himself master of the strong-hold of Zion (Sa2 5:6-10). III. Building himself a house and strengthening himself in his kingdom (Sa2 5:11, Sa2 5:12). IV. His children that were born after this (Sa2 5:13-16). V. His victories over the Philistines (Sa2 5:17-25).
