Exodus 23:20-24

“See, I am sending an angel before you to protect you on your journey and lead you safely to the place I have prepared for you. Pay close attention to him, and obey his instructions. Do not rebel against him, for he is my representative, and he will not forgive your rebellion. But if you are careful to obey him, following all my instructions, then I will be an enemy to your enemies, and I will oppose those who oppose you. For my angel will go before you and bring you into the land of the Amorites, Hittites, Perizzites, Canaanites, Hivites, and Jebusites, so you may live there. And I will destroy them completely. You must not worship the gods of these nations or serve them in any way or imitate their evil practices. Instead, you must utterly destroy them and smash their sacred pillars.
