Stricken of the Lord, David’s sister, and the mother of Abishai, Joab, and Asahel (1 Chr. 2:16), who were the three leading heroes of David’s army, and being his nephews, they were admitted to the closest companionship with him.
Zeruiah
“These men the sons of Zeruiah be too hard for me,” David says of Joab and Abishai, and he was king. Zeruiah was David’s sister, and her three sons, Joab, Abishai and Asahel, serve him as fighters, loyal and fierce. Asahel was “as light of foot as a wild roe.” When Shimei cursed the king, Abishai offered to “take off his head.” David told him to leave it alone, because the LORD had permitted the curse. The whole exchange is in 2 Samuel 16:9-11.
