You shall not bow down to them or serve them. For I the LORD your God am an impassioned God, visiting the guilt of the parents upon the children, upon the third and upon the fourth generations of those who reject Me, but showing kindness to the thousandth generation of those who love Me and keep My commandments.
Exodus 20:5-6
Whoever sacrifices to a god other than the LORD alone shall be proscribed.
Exodus 22:19
When My angel goes before you and brings you to the Amorites, the Hittites, the Perizzites, the Canaanites, the Hivites, and the Jebusites, and I annihilate them, you shall not bow down to their gods in worship or follow their practices, but shall tear them down and smash their pillars to bits.
Exodus 23:23-24
