Deuteronomy 4:16-19

16Do not make any image to be your god. That would be a sin. Do not make an image in any shape as your idol. Do not copy the shape of a man or a woman,

17or the shape of any animal or bird.

18Do not copy the shape of anything that moves along the ground, or any fish that swims in the deep water.

19When you look up at the sky, you see the sun, the moon and the stars. They all shine up in the sky. But do not bend down low to them or worship them. They are there because the Lord your God has made them. He has given them to people everywhere in the world.
