Deuteronomy 4:11-19; Deuteronomy 4:29

11 You came near and stood at the foot of the mountain while it blazed with fire to the very heavens, with black clouds and deep darkness. 12 Then the LORD spoke to you out of the fire. You heard the sound of words but saw no form; there was only a voice. 13 He declared to you his covenant, the Ten Commandments, which he commanded you to follow and then wrote them on two stone tablets. 14 And 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. 15 You saw no form of any kind the day the LORD spoke to you at Horeb out of the fire. Therefore watch yourselves very carefully, 16 so 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, 17 or like any animal on earth or any bird that flies in the air, 18 or like any creature that moves along the ground or any fish in the waters below. 19 And 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.
29 But if from there you seek the LORD your God, you will find him if you seek him with all your heart and with all your soul.
