Exodus 34:11-16 New King James Version (NKJV)
11 Observe what I command you this day. Behold, I am driving out from before you the Amorite and the Canaanite and the Hittite and the Perizzite and the Hivite and the Jebusite. 12 Take heed to yourself, lest you make a covenant with the inhabitants of the land where you are going, lest it be a snare in your midst. 13 But you shall destroy their altars, break their sacred pillars, and cut down their wooden images 14 (for you shall worship no other god, for the Lord, whose name is Jealous, is a jealous God), 15 lest you make a covenant with the inhabitants of the land, and they play the harlot with their gods and make sacrifice to their gods, and one of them invites you and you eat of his sacrifice, 16 and you take of his daughters for your sons, and his daughters play the harlot with their gods and make your sons play the harlot with their gods.
Exodus 34:11-16 New International Version (NIV)
11 Obey what I command you today. I will drive out before you the Amorites, Canaanites, Hittites, Perizzites, Hivites and Jebusites. 12 Be careful not to make a treaty with those who live in the land where you are going, or they will be a snare among you. 13 Break down their altars, smash their sacred stones and cut down their Asherah poles.[a] 14 Do not worship any other god, for the Lord, whose name is Jealous, is a jealous God.
15 “Be careful not to make a treaty with those who live in the land; for when they prostitute themselves to their gods and sacrifice to them, they will invite you and you will eat their sacrifices. 16 And when you choose some of their daughters as wives for your sons and those daughters prostitute themselves to their gods, they will lead your sons to do the same.
