The Gileadite; so called, either from his father Gilead, Joshua 17:1,2, or from the mountain or city of Gilead, the place of his birth or abode. The son of an harlot, i.e. a bastard; for though such were not ordinarily to enter into the congregation of the Lord, Deuteronomy 23:2, yet God can dispense with his own laws, and hath sometimes done honour to base-born persons, so far, that some of them were admitted to be the progenitors of the Lord Jesus Christ. Gilead; one of the children of that ancienter Gilead, Numbers 32:1 Joshua 17:1.
