Rashi on I Chronicles
Jether the Ishmaelite And in II Sam. (17:25) it says, “the Israelite.” He lived in the land of Ishmael, on the pattern of (ibid. 6:11): “the house of Obed Edom the Gittite,” and so, (I Ki. 7: 13f.): “And King Solomon sent and fetched Hiram out of Tyre. He (was) a widow’s son... and his father was a man of Tyre.”
