Abishai

"(To David, in front of the sleeping Saul) “God has delivered your enemy into your hand this day. Now therefore, please, let me strike him [a]at once with the spear, right to the earth; and I will not have to strike him a second time!”."

"Now the three sons of Zeruiah were there: Joab and Abishai and Asahel. And Asahel was as fleet of foot as a wild gazelle."

"Now their sisters were Zeruiah and Abigail. And the sons of Zeruiah were Abishai, Joab, and Asahel—three."

"So the two of them made a covenant before the Lord. And David stayed in the woods, and Jonathan went to his own house. Then the Ziphites came up to Saul at Gibeah, saying, “Is David not hiding with us in strongholds in the woods, in the hill of Hachilah, which is on the south of Jeshimon?"

"So David and Abishai came to the people by night; and there Saul lay sleeping within the camp, with his spear stuck in the ground by his head. And Abner and the people lay all around him. Then Abishai said to David, “God has delivered your enemy into your hand this day. Now therefore, please, let me strike him at once with the spear, right to the earth; and I will not have to strike him a second time!” But David said to Abishai, “Do not destroy him; for who can stretch out his hand against the Lord’s anointed, and be guiltless?” David said furthermore, “As the Lord lives, the Lord shall strike him, or his day shall come to die, or he shall go out to battle and perish."
