2 Samuel 23:13

13. Three of the thirty chief That is, of the thirty whose names are given in 2 Samuel 23:24-39. Their names are not designated here, and this reference to them is too indefinite to be understood of the three just mentioned, namely, Jashobeam, Eleazar, and Shammah.

Came to David Put themselves under his command when he was fleeing before Saul, and had taken refuge in the cave of Adullam. See 1 Samuel 22:1-2.

Pitched in… Rephaim This was in all probability the same battle as that described in 2 Samuel 5:17-21, and occurred after David had been anointed king over Israel, but before he had taken up his settled residence in Jerusalem. See notes at that place. It is not said that this exploit occurred at the time these heroes first joined David’s band of men, as some have assumed.
