15 Once when David was at the rock near the cave of Adullam, the Philistine army was camped in the valley of Rephaim. The Three (who were among the Thirty-an elite group among David's fighting men) went down to meet him there.

Matthew Henry's Commentary on 1 Chronicles 11:15

Commentary on 1 Chronicles 11:10-47

(Read 1 Chronicles 11:10-47)

An account is given of David's worthies, the great men who served him. Yet David reckoned his success, not as from the mighty men that were with him, but from the mighty God, whose presence is all in all. In strengthening him, they strengthened themselves and their own interest, for his advancement was theirs. We shall gain by what we do in our places for the support of the kingdom of the Son of David; and those that are faithful to Him, shall find their names registered much more to their honour, than these are in the records of fame.
