Leviticus 20:23

²³Do not ye go in the lawful things, that is, in worshipping and in the manner of living of them, of the nations, which I shall cast out before you, for they did all these things, and I had abomination of them. (Do not ye follow the laws, and the customs, of the nations which I shall throw out before you, for they did all these things, and I found them abominable.)
