Beth-aven
    house of nothingness; i.e., "of idols", a place in the mountains
    of Benjamin, east of Bethel (Josh. 7:2; 18:12; 1 Sam. 13:5). In
    Hos. 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.



 Beth-aven, the house of vanity; of iniquity of trouble
