Exodus 34:15-16

34:15 Be careful not to make a covenant with the inhabitants of the land, for when they prostitute themselves to their gods and sacrifice to their gods, and someone invites you, you will eat from his sacrifice; 34:16 and you then take his daughters for your sons, and when his daughters prostitute themselves to their gods, they will make your sons prostitute themselves to their gods as well.

Numbers 15:39

15:39 You must have this tassel so that you may look at it and remember all the commandments of the Lord and obey them and so that you do not follow after your own heart and your own eyes that lead you to unfaithfulness.

Psalms 73:27

73:27 Yes, look! Those far from you die;

you destroy everyone who is unfaithful to you.

Ezekiel 6:9

6:9 Then your survivors will remember me among the nations where they are exiled. They will realize how I was crushed by their unfaithful heart which turned from me and by their eyes which lusted after their idols. They will loathe themselves because of the evil they have done and because of all their abominable practices.

Hosea 4:12

4:12 They consult their wooden idols,

and their diviner’s staff answers with an oracle.

The wind of prostitution blows them astray;

they commit spiritual adultery against their God.
