NASB
"So Joab and Abishai his brother killed Abner because he had put their brother Asahel to death in the battle at Gibeon."
— 2 Samuel 3:30, NASB
“So Joab and Abishai his brother slew Abner, because he had slain their brother Asahel at Gibeon in the battle.”
“So Joab and Abishai his brother slew Abner, because he had killed their brother Asahel at Gibeon in the battle. ”
“So Joab and Abishai his brother killed Abner, because he had killed their brother Asahel at Gibeon in the battle.”
“So Joab and his brother Abishai killed Abner, because he had killed their brother Asahel in Gibeon during the battle.”
“So Joab and Abisai his brother slew Abner, because he had killed their brother Asael at Gabaon in the battle.”
“So Joab and Abishai his brother put Abner to death, because he had put to death their brother Asahel in the fight at Gibeon.”
“So Joab and Abishai his brother slew Abner, because he had slain their brother Asahel at Gibeon in the battle.”
So when Abner returned to Hebron, Joab took him aside into the middle of the gate to speak with him privately, and there he struck him in the belly so that he died on account of the blood of Asahel his brother.
Afterward when David heard it, he said, "I and my kingdom are innocent before the LORD forever of the blood of Abner the son of Ner.
"May it fall on the head of Joab and on all his father's house; and may there not fail from the house of Joab one who has a discharge, or who is a leper, or who takes hold of a distaff, or who falls by the sword, or who lacks bread."
So Joab and Abishai his brother killed Abner because he had put their brother Asahel to death in the battle at Gibeon.
Then David said to Joab and to all the people who were with him, "Tear your clothes and gird on sackcloth and lament before Abner." And King David walked behind the bier.
Thus they buried Abner in Hebron; and the king lifted up his voice and wept at the grave of Abner, and all the people wept.
The king chanted a lament for Abner and said, "Should Abner die as a fool dies?
