or ATROTH, (anc. geogr.) the name of several towns. Two appear to have been in Samaria, in the tribe of Ephraim; the one four miles to the north of Sebastae, or the city of Samaria; the other in the confines of Benjamin and Ephraim, yet so as to be of the resort of Ephraim rather than of Benjamin (Joshua). This is the Athroth-Addar mentioned Joshua xvi. 5, from which to Uzzer Bethoron extends the greatest breadth of the tribe of Ephraim.
