The conflict extended over the surface of the whole land, i.e., the whole of that region (the Chethib נפצות is not the plural נפצות, which would be quite unsuitable, but is most probably a noun, נפצוּת ,nuon a, signifying bursting asunder, or wild flight; the Keri נפצת is a Niphal participle, fem. gen.); "and the wood devoured more of the people than the sword ate on the same day." The woody region was most likely full of ravines, precipices, and marches, into which the flying foe was pursued, and where so many perished.

This chapter puts a period to Absalom's rebellion and life, and so makes way for David to his throne again, whither the next chapter brings him back in peace and triumph. We have here, I. David's preparations to engage the rebels (Sa2 18:1-5). II. The total defeat of Absalom's party and their dispersion (Sa2 18:6-8). III. The death of Absalom, and his burial (Sa2 18:9-18). IV. The bringing of the tidings to David, who tarried at Mahanaim (Sa2 18:19-32). V. His bitter lamentation for Absalom (Sa2 18:33).
