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.

and unfaithful in their actions.

Idolatrous Israel Will Be Punished Like a Prostitute

2:2 Plead earnestly with your mother

(for she is not my wife, and I am not her husband),

so that she might put an end to her adulterous lifestyle,

and turn away from her sexually immoral behavior.
