1 Chronicles 11:12-15

After him was Eleazar the son of Dodo, the Ahohite, who was one of the three mighty men. He was with David at Pasdammim. Now there the Philistines were gathered for battle, and there was a piece of ground full of barley. So the people fled from the Philistines. But they stationed themselves in the middle of that field, defended it, and killed the Philistines. So the Lord brought about a great victory.

Now three of the thirty chief men went down to the rock to David, into the cave of Adullam; and the army of the Philistines encamped in the Valley of Rephaim.
