Abishai

Their sisters were Zeruiah and Abigail. And the three sons of Zeruiah were Abishai, Joab, and Asahel.

Now Abishai, the brother of Joab, was chief of the Three, and he lifted his spear against three hundred men, killed them, and won a name along with the Three.

Moreover, Abishai son of Zeruiah struck down eighteen thousand Edomites in the Valley of Salt.

And he placed the rest of the forces under the command of his brother Abishai, who arrayed them against the Ammonites.

When the Ammonites saw that the Arameans had fled, they too fled before Joab’s brother Abishai, and they entered the city. So Joab went back to Jerusalem.

⁶ And David asked Ahimelech the Hittite and Abishai son of Zeruiah, Joab’s brother, “Who will go down with me to Saul in the camp?” “I will go with you,” answered Abishai.

⁷ That night David and Abishai came to the troops, and Saul was lying there asleep in the inner circle of the camp, with his spear stuck in the ground by his head. And Abner and the troops were lying around him.

⁸ Abishai said to David, “Today God has delivered your enemy into your hand. Now, therefore, please let me thrust the spear through him into the ground with one stroke. I will not need to strike him twice!”

⁹ But David said to Abishai, “Do not destroy him, for who can lift a hand against the LORD’s anointed and be guiltless?”

¹⁸ The three sons of Zeruiah were there: Joab, Abishai, and Asahel. Now Asahel was fleet of foot like a wild gazelle,

¹⁹ and he chased Abner, not turning to the right or to the left in his pursuit.

But Joab and Abishai pursued Abner. By sunset, they had gone as far as the hill of Ammah opposite Giah on the way to the wilderness of Gibeon.

(Joab and his brother Abishai murdered Abner because he had killed their brother Asahel in the battle at Gibeon.)

And he placed the rest of the forces under the command of his brother Abishai, who arrayed them against the Ammonites.
