When the Lord brings you into His land to take possession of it and He drives many nations out before, Hittites, Girgashites, Amorites, Canaanites, Perizzites, Hivites and Jebusites; seven nations who are stronger than you must exterminate them.
Make no covenant with them, no mercy, no marriages. Do not take your daughters for their sons. So that the Lord’s wrath does not burn against you. Tear down their altars, their sacred stones, holy pillars, burn their idols. For you are a holy people, the treasured possession of all the peoples of the earth. With a mighty hand He has led you out of servitude to the Pharaoh in Egypt. Know then that the Lord your God keeps his covenant of mercy to the thousandth member of those who love him and keep his commandments but will repay to their faces those who hate him and kill them. Keep the commandments, laws and judgments. that you heard today.

Promise of the holy blessing

If you do this the Lord will bless you and love you and increase all that you have. Noone among you will be barren, not even the animals. The Lord will take the sicknesses from you and not inflict any plagues or punishments upon you and inflict them instead on those that hate you. You will destroy all the peoples that the Lord delivers to you. Have no mercy upon them, do not worship their gods for this would be a snare to you.
If you say in your heart: these peoples are larger than me; how can I drive them out. Be not afraid of them. Think on the tests of power that you have seen done by signs and wonders, by mighty hand and outstretched arm.
Thus the Lord of all peoples whom you fear will do. He will drive fear and terror into them until they have been killed. Do not fear them. The Lord is in your midst, the great, the terrible. He will drive them out, singly and one after the other. You cannot destroy them all at once so that the wild animals do not multiply against you. He will bring confusion among them until they are destroyed. Deliver the kings into your hands. Noone will stand in your way. Burn their idols and do not take the silver or their gold that is on them so that you do become ensnared by it. This is a horror to God, the Lord. Do not bring it into your house that you do not fall under the same curse as them, rather detest it as vile for it is cursed.
