1 Chronicles 18:12

Then answered David and said to Ahimelech the Hittite, and to Abishai the son of Zeruiah, brother to Joab, saying, Who will go down with me to Saul to the camp? And Abishai said, I will go down with thee.

So Joab, and Abishai his brother slew Abner, because he had slain their brother Asahel at Gibeon in the battle.

And the rest of the people he delivered into the hand of Abishai his brother, that he might put them in array against the children of Ammon.

Then said Abishai the son of Zeruiah unto the king, Why should this dead dog curse my lord the king? let me go over, I pray thee, and take off his head. And the king said, What have I to do with you, ye sons of Zeruiah? so let him curse, because the LORD hath said unto him, Curse David. Who shall then say, Wherefore hast thou done so? And David said to Abishai, and to all his servants, Behold, my son, which came forth of my bowels, seeketh my life: how much more now may this Benjamite do it? let him alone, and let him curse; for the LORD hath bidden him.

But Abishai the son of Zeruiah answered and said, Shall not Shimei be put to death for this, because he cursed the LORD's anointed?

And David said to Abishai, Now shall Sheba the son of Bichri do us more harm than did Absalom: take thou thy lord's servants, and pursue after him, lest he get him fenced cities, and escape us.

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

And Abishai the brother of Joab, he was chief of the three: for lifting up his spear against three hundred, he slew them, and had a name among the three.
