Exodus 34:14-16

Revised Standard Version

¹⁴ (for you shall worship no other god, for the Lord, whose name is Jealous, is a jealous God), ¹⁵ lest you make a covenant with the inhabitants of the land, and when they play the harlot after their gods and sacrifice to their gods and one invites you, you eat of his sacrifice, ¹⁶ and you take of their daughters for your sons, and their daughters play the harlot after their gods and make your sons play the harlot after their gods.
