1 Chronicles 11:14

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.

After him was Eleazar the son of Dodo, the Ahohite, who was one of the three mighty men.

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.

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.

David was then in the stronghold, and the garrison of the Philistines was in Bethlehem at that time.

David longed, and said, “Oh, that someone would give me water to drink from the well of Bethlehem, which is by the gate!”
