2 Samuel 23:18-19

18Abishai was the leader of David's 30 great soldiers. He was the brother of Zeruiah's son Joab. One time, he used his spear to fight 300 men and he killed them all. So he became as famous as the ‘Three Brave Soldiers’.

19He was not one of the ‘Three Brave Soldiers’ but he received more honour than the other 30 great soldiers. So he became their leader.
