Matthew Poole and continuators on 2 Samuel 23:13

13 And three of the thirty chief went down and came to David, in the harvest-time, unto the cave of Adullam : and a Troop of the Philistines pitched in the valley of Rephaim .

Either 1. The Three already named, as is generally supposed, because it is said of them, in the close of this History, 1 Chron. 11. 19. These things did those three mightiest. But in the Hebrew it is onely, these three mighty men, as the same Words are rendred here, ver. 17. Or rather, 2. The following three: for it is expresly said, both here, ver. 16. and 1 Chron. 11. 20. That Abishai was chief, and therefore one of the three: and this Three are plainly distinguished from the first Three, ver. 19. and 1 Chron. 11. 25.

Which was a strong Place where David had been before, 1 Sam. 22. 1, &c. and where he had now again Fortified himself in the beginning of his Reign, when the Philistines were too strong for him.

Of which see above, Chap. 5. 18.
