Exodus 23:20-25

“Behold, I send an angel before you to guard you on the way and to bring you to the place that I have prepared. Pay careful attention to him and obey his voice; do not rebel against him, for he will not pardon your transgression, for my name is in him. “But if you carefully obey his voice and do all that I say, then I will be an enemy to your enemies and an adversary to your adversaries. “When my angel goes before you and brings you to the Amorites and the Hittites and the Perizzites and the Canaanites, the Hivites and the Jebusites, and I blot them out, you shall not bow down to their gods nor serve them, nor do as they do, but you shall utterly overthrow them and break their pillars in pieces. You shall serve the LORD your God, and he will bless your bread and your water, and I will take sickness away from among you.
