Deuteronomy 4:2 Do not add to what I command you and do not subtract from it, but keep the commands of the LORD your God that I give you

If you make an altar of stones for me, do not build it with dressed stones, for you will defile it if you use a tool on it. He took what they handed him and made it into an idol cast in the shape of a calf, fashioning it with a tool. Then they said, “These are your gods, Israel, who brought you up out of Egypt.”These people worship me in vain; their teachings are merely human rules as a dog returns to its vomit, so fools repeat their folly. Then will I profess unto them, I never knew you: depart from me, ye that work iniquity
