Deuteronomy 4:11-15

NHEB(i) 11 You came near and stood under the mountain; and the mountain burned with fire to the heart of the sky, with darkness, cloud, and thick darkness. 12 The LORD spoke to you out of the midst of the fire: you heard the voice of words, but you saw no form; you only heard a voice. 13 He declared to you his covenant, which he commanded you to perform, even the ten commandments; and he wrote them on two tablets of stone. 14 The LORD commanded me at that time to teach you statutes and ordinances, that you might do them in the land where you go over to possess it. 15 Therefore watch yourselves carefully; for you saw no kind of form on the day that the LORD spoke to you in Horeb out of the midst of the fire.
