Geshur was a territory in the northern part of Bashan, in ancient Levant, adjoining the province of Argob (Deuteronomy 3:14) and the kingdom of Aram or Syria. (2 Samuel 15:8; 1 Chronicles 2:23) It was allotted to the half-tribe of Manasseh, which settled east of the Jordan river; but its inhabitants, the Geshurites, could not be expelled. (Joshua 13:13)
In the time of David, Geshur was an independent kingdom, and David married Maachah, a daughter of Talmai, king of Geshur. (2 Samuel 3:3, 1 Chronicles 3:2) Her son Absalom fled to his mother's native country, after the murder of his half-brother and David's eldest son, Amnon. Absalom stayed there for three years before being rehabilitated by David. (ib. 13:37, 15:8)
Geshur is identified with the plateau called today "Lejah," in the center of the Hauran.
