House of the desert, one of the six cities of Judah, situated in the sunk valley of the Jordan and Dead Sea (Josh. 18:22). In Josh. 15:61 it is said to have been “in the wilderness.” It was afterwards included in the towns of Benjamin. It is called Arabah (Josh. 18:18).
Beth-Arabah
Some places are known only from a boundary line. Betharabah is one of them: a point on the border between Judah and Benjamin, passed “by the north of Betharabah” (Joshua 15:6). Joshua also lists it among Judah’s cities “in the wilderness” (Joshua 15:61). The nearby verse in Joshua 18 follows the same border and speaks of the side “over against Arabah northward.” Nothing in these verses tells a story about it. The name simply helps mark where one tribe’s land ended and another’s began. Joshua 15:1-12 traces the line.

Joshua
And the border went up to Bethhogla, and passed along by the north of Betharabah; and the border went up to the stone of Bohan the son of Reuben:
In the wilderness, Betharabah, Middin, and Secacah,
And passed along toward the side over against Arabah northward, and went down unto Arabah:
