Deuteronomy 4:14-19

14And the LORD directed me at that time to teach you the decrees and laws you are to follow in the land that you are crossing the Jordan to possess.

Idolatry Forbidden 15You saw no form of any kind the day the LORD spoke to you at Horeb out of the fire. Therefore watch yourselves very carefully, 16so that you do not become corrupt and make for yourselves an idol, an image of any shape, whether formed like a man or a woman, 17or like any animal on earth or any bird that flies in the air, 18or like any creature that moves along the ground or any fish in the waters below. 19And when you look up to the sky and see the sun, the moon and the stars—all the heavenly array—do not be enticed into bowing down to them and worshiping things the LORD your God has apportioned to all the nations under heaven.
