2 Samuel 17:25

Ithra an Israelite. In 1 Chronicles 2:17 he is called "Jether the Ishmeelite." The first name is the same, Ithra being the emphatic form of Jether; and as it is difficult to find a reason for mentioning so ordinary a fact as that his father was an Israelite, we may conclude that "Ishmeelite" is the correct reading. Bishop Wordsworth, however, suggests that "Israelite" was in contrast to "Judahite;" but this distinction did not come into use until after the disruption of the kingdom. The Vatican text of the Septuagint has "Jezreelite," which is probably a conjecture to get rid of the obvious error of calling him an Israelite. Amasa was an illegitimate son, which confirms the reading "Ishmeelite" in 1 Chronicles 2:17 , as a marriage between Abigail and a foreigner would be sure to be opposed by all the members of Jesse's family. Nahash . Jewish interpreters regard Nahash (equivalent to "serpent") as another name for Jesse, quoting in proof, "Out of the root of Nahash (the serpent) shall come forth the basilisk" ( Isaiah 14:29 ), which in the Chaldee Paraphrase is explained as meaning, "out of the root of Jesse shall come forth the Messiah." This conceit would scarcely have deserved mention, had it not found a place in the margin of the Authorized Version. Some few commentators regard Nahash as a woman's name, and think that she was a wife of Jesse, and mother of Abigail and Zerniah, but not of David. But Nahash is so constantly a man's name that it is easier to believe that Nahash was the first husband of David's mother, and Abigail and Zerniah his half-sisters, not on the father's, but on the mother's side. Joab and his brothers are always described as sons of Zeruiah, both to mark their relationship to David, and also because the rank was on her side. Amasa was probably the Amasai mentioned in 1 Chronicles 12:18 as bringing a powerful reinforcement to David while at Ziklag; but the ambition of supplanting Joab made him now forget David's long friendship.
