Abishai

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

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

“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.”

“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.)”

“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 Abishai, and they entered the city. So Joab returned from fighting against the Ammonites and came to Jerusalem.”
