II Samuel 23:13

13 During harvest time, three of the thirty chief warriors came down to David at the cave of Adullam, while a band of Philistines was encamped in the Valley of Rephaim.

13 And three of the thirty went down at the start of the grain-cutting, and they came to David at the strong place of Adullam; and the band of Philistines had taken up their position in the valley of Rephaim.
