Jabbok (jăb'bok), emptying. A stream rising about 25 miles east of the north end of the Dead sea, and flowing east, then northward and westward, and finally into the Jordan about midway between the Sea of Galilee and the Dead sea. It is now called the Zerka or "blue" river. Across this stream Jacob sent his family, and here his wrestling for a blessing occurred. Genesis 32:22-24. The Israelites conquered the kingdoms of Og and Sihon, but not the Ammonite country nor the upper Jabbok, which explains Deuteronomy 2:37. Compare Numbers 21:24; Deuteronomy 3:16; Joshua 12:2; Judges 11:13; Judges 11:22. The Jabbok, before it enters the Jordan valley, flows through a deep, narrow ravine, the hills being from 1500 to 2000 feet in height. The stream abounds in small fish of excellent flavor.
