1 Chronicles 2:17

And Abigail bare Amasa,.... Who was Absalom's general, afterwards reconciled to David, and designed to be made general of his army, but was slain by Joab, see 2 Samuel 17:25,

and the father of Amasa was Jether the Ishmaelite; he is called an Israelite, 2 Samuel 17:25, and so in the Targum here, he being either a proselyte, or else he was an Israelite by birth, but called an Ishmaelite, because he had dwelt among the Ishmaelites some time, as Obededom is called the Gittite for the like reason; so Jarchi and Kimchi interpret it.
