Ataroth-addar in the Bible

And the border of the children of Ephraim according to their families was thus : the border of their inheritance eastward was Ataroth-addar, unto Beth-horon the upper;

And the border passed along from thence to Luz, to the side of Luz (the same is Beth-el), southward; and the border went down to Ataroth-addar, by the mountain that lieth on the south of Beth-horon the nether.
