Deuteronomy 7:2-11

2and when the LORD your God has delivered them over to you to defeat them, then you must devote them to complete destruction.1 Make no treaty2 with them and show them no mercy.

3Do not intermarry with them. Do not give your daughters to their sons or take their daughters for your sons, 4because they will turn your sons away from following Me to serve other gods. Then the anger of the LORD will burn against you, and He will swiftly destroy you.

5Instead, this is what you are to do to them: tear down their altars, smash their sacred pillars, cut down their Asherah poles, and burn their idols in the fire. 6For you are a people holy to the LORD your God. The LORD your God has chosen you to be a people for His prized possession out of all peoples on the face of the earth.

7The LORD did not set His affection on you and choose you because you were more numerous than the other peoples, for you were the fewest of all peoples. 8But because the LORD loved you and kept the oath He swore to your fathers, He brought you out with a mighty hand and redeemed you from the house of slavery, from the hand of Pharaoh king of Egypt.

9Know therefore that the LORD your God is God, the faithful God who keeps His covenant of loving devotion for a thousand generations of those who love Him and keep His commandments. 10But those who hate Him He repays to their faces with destruction; He will not hesitate to repay to his face the one who hates Him.

11So keep the commandments and statutes and ordinances that I am giving you to follow this day.
