Exodus

Thou shalt have no other gods before me.

As for you, O house of Israel, thus saith the Lord God; Go ye, serve ye every one his idols, and hereafter also, if ye will not hearken unto me: but pollute ye my holy name no more with your gifts, and with your idols.

Turn ye not unto idols, nor make to yourselves molten gods: I am the Lord your God.

They have turned aside quickly out of the way which I commanded them: they have made them a molten calf, and have worshipped it, and have sacrificed thereunto, and said, These be thy gods, O Israel, which have brought thee up out of the land of Egypt.

And Moses returned unto the Lord, and said, Oh, this people have sinned a great sin, and have made them gods of gold.
