BETH AVEN (bĕth' ā'vĕn, Heb. bēth’āwen, house of vanity). A town on the northern mountains of Benjamin (Josh.18.12), beside Ai, east of Bethel (Josh.7.2) and west of Michmash (1Sam.13.5; 1Sam.14.23). The name is used by Hosea (1Sam.4.15; 1Sam.5.8; 1Sam.10.5) to reveal the fallen condition of Bethel due to the idolatry introduced by King Jeroboam. The house of God (Bethel) had become the house of vanity and idolatry (Beth Aven).
