Deuteronomy 7:2-16

2And when the LORD thy God shall deliver them before thee; thou shalt smite them, and utterly destroy them; thou shalt make no covenant with them, nor show mercy to them: 3Neither shalt thou make marriages with them; thy daughter thou shalt not give to his son, nor his daughter shalt thou take to thy son. 4For they will turn away thy son from following me, that they may serve other gods: so will the anger of the LORD be kindled against you, and destroy thee suddenly. 5But thus shall ye deal with them; ye shall destroy their altars, and break down their images, and cut down their groves, and burn their graven images with fire.1 6For thou art an holy people to the LORD thy God: the LORD thy God hath chosen thee to be a special people to himself, above all people that are upon the face of the earth. 7The LORD did not set his love upon you, nor choose you, because ye were more in number than any people; for ye were the fewest of all people: 8But because the LORD loved you, and because he would keep the oath which he had sworn to your fathers, hath the LORD brought you out with a mighty hand, and redeemed you from the house of bondage, from the hand of Pharaoh king of Egypt. 9Know therefore that the LORD thy God, he is God, the faithful God, who keepeth covenant and mercy with them that love him and keep his commandments to a thousand generations; 10And repayeth them that hate him to their face, to destroy them: he will not be slack to him that hateth him, he will repay him to his face. 11Thou shalt therefore keep the commandments, and the statutes, and the judgments, which I command thee this day, to do them.

12Therefore it shall come to pass, if ye hearken to these judgments, and keep, and do them, that the LORD thy God shall keep to thee the covenant and the mercy which he swore to thy fathers:2 13And he will love thee, and bless thee, and multiply thee: he will also bless the fruit of thy womb, and the fruit of thy land, thy grain, and thy wine, and thy oil, the increase of thy cattle, and the flocks of thy sheep, in the land which he swore to thy fathers to give thee. 14Thou shalt be blessed above all people: there shall not be male or female barren among you, or among your cattle. 15And the LORD will take away from thee all sickness, and will put none of the evil diseases of Egypt, which thou knowest, upon thee; but will lay them upon all them that hate thee. 16And thou shalt consume all the people which the LORD thy God shall deliver to thee; thy eye shall have no pity upon them: neither shalt thou serve their gods; for that will be a snare to thee.
