Deuteronomy 7:1-4

ECB(i) 1
THE TORAH ON MINGLING When Yah Veh your Elohim brings you to the land where you go, to possess it, and plucks many goyim from your face - the Hethiy and the Girgashiy and the Emoriy and the Kenaaniy and the Perizziy and the Hivviy and the Yebusiy - seven goyim greater and mightier than you; 2 and when Yah Veh your Elohim gives them at your face, smite them; and in devoting, devote them: neither cut a covenant with them nor grant charism to them: 3 neither intermarry with them; nor give your daughter to his son, nor take his daughter to your son. 4 For he turns aside your son from following me to serve other elohim: so that Yah Veh kindles his wrath against you and destroys you suddenly.
