'Valley of Hinnom' in the Bible

The border went up by the valley of the son of Hinnom to the side of the Jebusite southward (the same is Jerusalem); and the border went up to the top of the mountain that lies before the valley of Hinnom westward, which is at the farthest part of the valley of Rephaim northward.

The border went down to the farthest part of the mountain that lies before the valley of the son of Hinnom, which is in the valley of Rephaim northward. It went down to the valley of Hinnom, to the side of the Jebusite southward, and went down to En Rogel.

Zanoah, Adullam, and their villages, Lachish and its fields, Azekah and its towns. So they encamped from Beersheba to the valley of Hinnom.
