Exodus 34:15

And they called the people unto the sacrifices of their gods: and the people did eat, and bowed down to their gods.

And yet they would not hearken unto their judges, but they went a whoring after other gods, and bowed themselves unto them: they turned quickly out of the way which their fathers walked in, obeying the commandments of the LORD; but they did not so.

And they shall no more offer their sacrifices unto devils, after whom they have gone a whoring. This shall be a statute for ever unto them throughout their generations.

Take heed to thyself, lest thou make a covenant with the inhabitants of the land whither thou goest, lest it be for a snare in the midst of thee:

For if any man see thee which hast knowledge sit at meat in the idol's temple, shall not the conscience of him which is weak be emboldened to eat those things which are offered to idols; emboldened: Gr. edified

Howbeit there is not in every man that knowledge: for some with conscience of the idol unto this hour eat it as a thing offered unto an idol; and their conscience being weak is defiled.

Thou shalt make no covenant with them, nor with their gods.
