Ex 23:20-26

Reward of Fidelity. 20See, I am sending an angel^j 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.
