Arabah in the Bible

Abner and his men went through the Arabah all that night. They crossed the Jordan River and went through the whole region of Bitron and came to Mahanaim.

They had entered the house while Ish-bosheth was resting on his bed in his bedroom. They mortally wounded him and then cut off his head. Taking his head, they traveled on the way of the Arabah all that night.
