Ex 23:20-29
Reward of Fidelity. 20See, I am sending an angelj before you, to guard you on the way and bring you to the place I have prepared. 21Be attentive to him and obey him. Do not rebel against him, for he will not forgive your sin. My authority is within him.* 22If you obey him and carry out all I tell you, I will be an enemy to your enemies and a foe to your foes.
23My angel will go before you and bring you to the Amorites, Hittites, Perizzites, Canaanites, Hivites and Jebusites; and I will wipe them out. 24Therefore, you shall not bow down to their gods and serve them, nor shall you act as they do; rather, you must demolish them and smash their sacred stones.* k 25You shall serve the LORD, your God; then he will bless your food and drink, and I will remove sickness from your midst; 26no woman in your land will be barren or miscarry; and I will give you a full span of life.
27I will have the terror of me precede you, so that I will throw into panic every nation you reach.l I will make all your enemies turn from you in flight, 28and ahead of you I will send hornets* to drive the Hivites, Canaanites and Hittites out of your way. 29But I will not drive them all out before you in one year, lest the land become desolate and the wild animals multiply against you.
