Albert Barnes Commentary Joshua 16:2

"and it went out from Beth-el to Luz, and passed along unto the border of the Archites to Ataroth;" — Joshua 16:2 (ASV)

Of Archi - (Read “of the Archite,” also a designation of David’s friend Hushai (2 Samuel 15:32; 2 Samuel 16:16 and following).). The word is derived from Erech (Genesis 10:10). But whether there was in the neighborhood of Bethel a place bearing this Babylonian name, or whether a colony from the East had settled in this spot and brought the name with them, is unknown.

Ataroth - Called (Joshua 16:5; Joshua 18:13) Ataroth-adar (= “crowns of fame or greatness”) perhaps to distinguish it from two other places bearing the same name, but situated on the other side of Jordan, in the territory of Gad (Numbers 32:34). It is identified with Atara, near the road from Jerusalem to Nablous.
