Exodus 34:16

16and you take of atheir daughters for your sons, and their daughters bwhore after their gods and make your sons whore after their gods.

Deuteronomy 7:1-4

A Chosen People

1“When the cLord your God brings you into the land that you are entering to take possession of it, and clears away many nations before you, dthe Hittites, the Girgashites, the Amorites, the Canaanites, the Perizzites, the Hivites, and the Jebusites, seven nations emore numerous and mightier than you, 2 fand when the Lord your God gives them over to you, and you defeat them, then you must gdevote them to complete destruction.
That is, set apart ( devote) as an offering to the Lord (for destruction)
iYou shall make no covenant with them and show no mercy to them.
3 jYou shall not intermarry with them, giving your daughters to their sons or taking their daughters for your sons, 4for they would turn away your sons from following me, to serve other gods. kThen the anger of the Lord would be kindled against you, and he would destroy you lquickly.

Ezra 10:18-44
