1 Kings 16:13

Vanities — that is, idols (as in Deuteronomy 32:21; 1 Samuel 12:21; Psalms 31:6; Isaiah 41:29; Jer. viii 19; &c.): not only the idols of Dan and Bethel, but the worse abominations which grew up under cover of these. In the Old Testament generally the contempt for idolatry and false worship as a gross folly, wasting faith on unrealities, is at least as strong as the condemnation of them, as outraging God’s law, and connected with sensual or bloody rites. (See, for example, the utter scorn of Isaiah 44:9; Psalms 115:4.)
