Ataroth-addar in the Bible

Now this was the territory of the sons of Ephraim according to their families: on the east side the border of their inheritance was Ataroth-addar, as far as upper Beth-horon.

Then the border continued southward toward Luz, to the slope of Luz (that is, Bethel); then the border went down to Ataroth-addar, by the hill that lies south of lower Beth-horon.
