Now Abishai, the brother of Joab, was chief of the Thirty. With his spear he fought against three hundred and killed them and won a name beside the Three.
And David sent forth the army: one third under the command of Joab; one third under the command of Abishai son of Zeruiah, Joab’s brother; and one third under the command of Ittai the Gittite. The king said to the men, “I myself will also go out with you.”
David said to Abishai, “Now Sheba son of Bichri will do us more harm than Absalom; take your lord’s servants and pursue him, or he will find fortified cities for himself and escape from us.”
But Abishai son of Zeruiah came to his aid and attacked the Philistine and killed him. Then David’s men swore to him, “You shall not go out with us to battle any longer, so that you do not quench the lamp of Israel.”
and said, “My God forbid that I should do this. Can I drink the blood of these men? For at the risk of their lives they brought it.” Therefore he would not drink it. The three warriors did these things.
Then David said to Ahimelech the Hittite and to Joab’s brother Abishai son of Zeruiah, “Who will go down with me into the camp to Saul?” Abishai said, “I will go down with you.”
