1 Chronicles 11:12

David grew greater and greater, for the LORD of Armies was with him.

Now these are the chief of the mighty men whom David had, who showed themselves strong with him in his kingdom, together with all Israel, to make him king, according to the LORD’s word concerning Israel.

This is the number of the mighty men whom David had: Jashobeam, the son of a Hachmonite, the chief of the thirty; he lifted up his spear against three hundred and killed them at one time.

He was with David at Pasdammim, and there the Philistines were gathered together to battle, where there was a plot of ground full of barley; and the people fled from before the Philistines.

They stood in the middle of the plot, defended it, and killed the Philistines; and the LORD saved them by a great victory.

Three of the thirty chief men went down to the rock to David, into the cave of Adullam; and the army of the Philistines were encamped in the valley of Rephaim.
