Deuteronomy 4:15

11 You came near and stood at the base of the mountain, a mountain blazing with fire to the heavens, with black clouds and deep darkness.

12 And the LORD spoke to you out of the fire. You heard the sound of the words, but saw no form; there was only a voice.

13 He declared to you His covenant, which He commanded you to follow—the Ten Commandments that He wrote on two tablets of stone.

14 At that time the LORD commanded me to teach you the statutes and ordinances you are to follow in the land that you are crossing the Jordan to possess.

15 So since you saw no form of any kind on the day the LORD spoke to you out of the fire at Horeb, be careful

16 that you do not act corruptly and make an idol for yourselves of any form or shape, whether in the likeness of a male or female,

17 of any beast that is on the earth or bird that flies in the air,

18 or of any creature that crawls on the ground or fish that is in the waters below.

19 When you look to the heavens and see the sun and moon and stars—all the host of heaven—do not be enticed to bow down and worship what the LORD your God has apportioned to all the nations under heaven.
