Deuteronomy 4:11-13 World English Bible (WEB)
11 You came near and stood under the mountain. The mountain burned with fire to the heart of the sky, with darkness, cloud, and thick darkness. 12 Yahweh spoke to you out of the middle 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. He wrote them on two stone tablets.
