Deuteronomy 7:2-16

2and when the Lord your God gives them over to you and you defeat them, then you shall utterly destroy them. You shall not make a covenant (treaty) with them nor show mercy and compassion to them.

3You shall not intermarry with them; you shall not give your daughter to his son, nor shall you take his daughter for your son;

4for they will turn your sons away from following Me to serve other gods; then the anger of the Lord will be kindled and burn against you and He will quickly destroy you.

5But this is how you shall deal with them: you shall tear down their altars and smash to pieces their sacred pillars, and cut down their Asherim (symbols of the goddess Asherah), and burn their carved or sculpted images in the fire.

6For you are a holy people [set apart] to the Lord your God; the Lord your God has chosen you out of all the peoples on the face of the earth to be a people for His own possession [that is, His very special treasure].

7“The Lord did not love you and choose you because you were greater in number than any of the other peoples, for you were the fewest of all peoples.

8But because the Lord loves you and is keeping the oath which He swore to your fathers, the Lord has brought you out with a mighty hand and redeemed (bought) you from the house of slavery, from the hand of Pharaoh king of Egypt.

9Therefore know [without any doubt] and understand that the Lord your God, He is God, the faithful God, who is keeping His covenant and His [steadfast] lovingkindness to a thousand generations with those who love Him and keep His commandments;

10but repays those who hate Him to their faces, by destroying them; He will not hesitate with him who hates Him, He will repay him to his face.

11Therefore, you shall keep (follow, obey) the commandment and the statutes and judgments (precepts) which I am commanding you today.

12“Then it shall come about, because you listen to these judgments and keep and do them, that the Lord your God will keep with you the covenant and the [steadfast] lovingkindness which He swore to your fathers.

13He will love you and bless you and multiply you; He will also bless the fruit of your womb and the fruit of your land, your grain and your new wine and your [olive] oil, the offspring of your cattle and the young of your flock, in the land which He swore to your fathers to give you.

14You shall be blessed above all peoples; there will be no male or female barren (childless, infertile) among you or among your cattle.

15The Lord will take away from you all sickness; and He will not subject you to any of the harmful diseases of Egypt which you have known, but He will impose them on all [those] who hate you.

16And you shall consume all the peoples whom the Lord your God will give over to you; your eye shall not pity them, nor shall you serve their gods, for that would be a [deadly] trap to you.
