Thematic Bible: Who not to make a covenant with

I will set your borders from the Red Sea to the Sea of the Philistines, and from the wilderness to the river [Euphrates]; for I will deliver the inhabitants of the land into your hand and you shall drive them out before you. You shall make no covenant with them or with their gods.

Observe what I command you this day. Behold, I drive out before you the Amorite, Canaanite, Hittite, Perizzite, Hivite, and Jebusite. Take heed to yourself, lest you make a covenant or mutual agreement with the inhabitants of the land to which you go, lest it become a snare in the midst of you. But you shall destroy their altars, dash in pieces their pillars (obelisks, images), and cut down their Asherim [symbols of the goddess Asherah]; read more.
For you shall worship no other god; for the Lord, Whose name is Jealous, is a jealous (impassioned) God, Lest you make a covenant with the inhabitants of the land, and when they play the harlot after their gods and sacrifice to their gods and one invites you, you eat of his food sacrificed to idols, And you take of their daughters for your sons, and their daughters play the harlot after their gods and make your sons play the harlot after their gods.

When the Lord your God brings you into the land which you are entering to possess and has plucked away many nations before you, the Hittites, the Girgashites, the Amorites, the Canaanites, the Perizzites, the Hivites, and the Jebusites, seven nations greater and mightier than you, And when the Lord your God gives them over to you and you smite them, then you must utterly destroy them. You shall make no covenant with them, or show mercy to them.
