2:3 The sons of Judah:
Er, Onan, and Shelah. These three were born to him by Bathshua, a Canaanite woman. Er, Judah’s firstborn, displeased the Lord, so the Lord killed him.
Jashobeam, a Hacmonite, was head of the officers. He killed three hundred men with his spear in a single battle.
11:15 Three of the thirty leaders went down to David at the rocky cliff at the cave of Adullam, while a Philistine force was camped in the Valley of Rephaim.
