6 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?" Abishai said, "I will go down with you."
*Minor differences ignored. Grouped by changes, with first version listed as example.
Ahimelech the Hittite - Only mentioned here. Uriah was also a Hittite.
Abishai - He was son of Zeruiah, David's sister, but probably about the same age as David. He because very famous as a warrior 2-Samuel 23:18, but was implicated with his brother Joab in the murder of Abner in retaliation for the death of their brother Asahel 2-Samuel 3:30.
Abishai the son of Zeruiah - She was David's sister; and therefore Abishai and Joab were nephews to David.
Then answered David and said to Ahimelech the (b) Hittite, and to Abishai the son of Zeruiah, brother to (c) Joab, saying, Who will go down with me to Saul to the camp? And Abishai said, I will go down with thee.
(b) Who was a stranger, and not an Israelite.
(c) Who afterward was David's chief captain.
Then answered David,.... Or addressed himself to the two following persons:
and said to Ahimelech the Hittite; who was either an Hittite by birth, but was become a proselyte, or he was an Israelite that had dwelt among the Hittites, and so had this name given him; the former seems most probable; some say (k) this was Uriah the Hittite:
and to Abishai the son of Zeruiah, brother to Joab; Zeruiah was the sister of David, 1-Chronicles 2:15; and these were two sons of hers, who very probably joined David at the cave of Adullam, 1-Samuel 22:1,
saying, who will go down with me to Saul to the camp? that is, which of you two?
and Abishai said, I will go down with thee; the other being timorous, or Abishai being most forward spoke first.
(k) Hieron. Trad. Hebrews. in lib. Reg. fol. 76. M.
Zerujah - David's sister. His father is not named either because he was now dead; or because he was an obscure person.
