Gilead

hill of testimony, (Gen. 31:21), a mountainous region east of
Jordan. From its mountainous character it is called "the mount
of Gilead" (Gen. 31:25). It is called also "the land of Gilead"
(Num. 32:1), and sometimes simply "Gilead" (Ps. 60:7; Gen.
37:25). It comprised the possessions of the tribes of Gad and
Reuben and the south part of Manasseh (Deut. 3:13; Num. 32:40).
It was bounded on the north by Bashan, and on the south by Moab
and Ammon (Gen. 31:21; Deut. 3:12-17). "Half Gilead" was
possessed by Sihon, and the other half, separated from it by the
river Jabbok, by Og, king of Bashan. The deep ravine of the
river Hieromax (the modern Sheriat el-Mandhur) separated Bashan
from Gilead, which was about 60 miles in length and 20 in
breadth, extending from near the south end of the Lake of
Gennesaret to the north end of the Dead Sea. Abarim, Pisgah,
Nebo, and Peor are its mountains mentioned in Scripture.
