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
Bethaven is a place near Ai and Bethel, and it shows up on both sides of Israel’s story. In Joshua 7:2 spies are sent from Jericho to Ai, “which is beside Bethaven.” In 1 Samuel 13 the Philistines pitch camp at Michmash, east of it, and in chapter 14 the battle passes over to Bethaven after the Lord saves Israel. Hosea later uses the name pointedly, telling the people “neither go ye up to Bethaven,” and speaks of “the calves of Bethaven,” a place now tied to false worship rather than to a landmark.
