Easton's Bible Dictionary (1897)
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). He slew the
Philistine giant Ishbi-benob, who threatened David’s life (2 Sam. 21:15-17). He was the chief of the second rank of the three “mighties” (2 Sam. 23:18, 19; 1 Chr. 11:20, 21); and on one occasion withstood 300 men, and slew them with his own spear (2 Sam. 23:18). Abishai is the name of the Semitic chief who offers gifts to the lord of Beni-Hassan. See illustration facing page 10.
Hastings' Dictionary of the Bible (1898) & Schaff's Bible Dictionary
ABISH'AI (father of a gift), the eldest son of Zeruiah, David's sister, and among the chief of his mighty men. 2 Sam 2:18. He accompanied David to the camp of Saul, and counselled him to take Saul's life, which David refused to do, 1 Sam 26:5-12, and was probably with David during the latter's wandering life. He was associated with Joab in the assassination of Abner. 2 Sam 3:30. The victory over the Edomites in the valley of Salt, which is
ascribed to David in 2 Sam 8:13, is ascribed to Abishai in 1 Chr 18:12. Probably Abishai actually obtained the victory, but as he was an officer under David, it might also with propriety be spoken of as David's achievement. Abishai, with Joab his brother, attacked and defeated the Syrians and the children of Ammon. 2 Sam 10. David appointed him, in conjunction with Joab and Ittai, to the command of the people when they went forth to battle
against Israel in the wood of Ephraim. 2 Sam 18:2. He afterward rescued David from the giant Philistine, Ishbi-benob, whom he smote and killed. 2 Sam 21:16, 2 Sam 21:17.
