Jair the son of Manasseh took all the country of Argob unto the coasts of Geshuri and Maachathi; and called them after his own name, Bashanhavothjair, unto this day. (Deuteronomy 3:14)
His mother was of the tribe of Manasseh, but his father was of the tribe of Judah (see 1 Chron. 2:22). Jair had conquered this territory, which was, accordingly, given to him and his descendants (Num. 32:41).
