(emptying), a stream which intersects the mountain range of Gilead (Joshua 12:2, 5) and falls into the Jordan on the east about midway between the Sea of Galilee and the Dead Sea. It was anciently the border of the children of Ammon (Numbers 21:24; Deuteronomy 2:37; 3:16). It was on the south bank of the Jabbok that the interview took place between Jacob and Esau (Genesis 32:22), and this river afterward became, toward its western part, the boundary between the kingdoms of Sihon and Og (Joshua 12:2, 5). Its modern name is Wady Zurka.
