Exodus 23 (NIV)
20“See, I am sending an angel ahead of you to guard you along the way and to bring you to the place I have prepared. 21Pay attention to him and listen to what he says. Do not rebel against him; he will not forgive your rebellion, since my Name is in him. 22If you listen carefully to what he says and do all that I say, I will be an enemy to your enemies and will oppose those who oppose you. 23My angel will go ahead of you and bring you into the land of the Amorites, Hittites, Perizzites, Canaanites, Hivites and Jebusites, and I will wipe them out. 24Do not bow down before their gods or worship them or follow their practices. You must demolish them and break their sacred stones to pieces. 25Worship the Lord your God, and his blessing will be on your food and water. I will take away sickness from among you, 26and none will miscarry or be barren in your land. I will give you a full life span.
27“I will send my terror ahead of you and throw into confusion every nation you encounter. I will make all your enemies turn their backs and run. 28I will send the hornet ahead of you to drive the Hivites, Canaanites and Hittites out of your way.
