Abishai was the father of (i.e., "desirous of") a gift, the eldest son of Zeruiah,
David's sister. He was the brother of
Joab and
Asahel (2 Sam. 2:18; 1 Chr. 2:16). Abishai was the only one who accompanied David when he went to the camp of
Saul and took the spear and the cruse of water from Saul's bolster (1 Sam. 26:5–12). He had the command of one of the three divisions of David's army at the battle with
Absalom (2 Sam. 18:2,5,12).
