|Easton's Bible Dictionary|
House of nothingness; i.e., "of idols", a place in the mountains of Benjamin, east of Bethel (Joshua 7:2; 18:12; 1 Samuel 13:5). In Hosea 4:15; 5:8; 10:5 it stands for "Bethel" (q.v.), and it is so called because it was no longer the "house of God," but "the house of idols," referring to the calves there worshipped.
Int. Standard Bible Encyclopedia
beth-a'-ven (beth 'awen; Baithon, Baithaun): A place on the northern boundary of the territory of Benjamin (Joshua 18:12) East of Bethel, near Ai (Joshua 7:2), West of Michmash (1 Samuel 13:5; 1 Samuel 14:23). Beth-aven, "house of vanity," i.e. "idolatry," may possibly represent an original beth-'on, "house of wealth." Wilson (PEFS, 1869, 126) suggests Khirbet An, West of Michmash. The name is used in mockery for Bethel by Hosea (4:15; 10:5, 8, etc.; compare Amos 5:5).
