12 Then Yahweh told Mosheh (Moses), “Come up to me on the mountain and wait there, and I will give you some stone slabs with the rules and regulations that I have written on them so you can to teach them to the people.” 13 So Mosheh and his assistant Yehoshua (Joshua) set off, and Mosheh climbed up God’s mountain. 14 He had already told the elders, “Wait for us down here in this place until we return here to you all. And see, Aharon (Aaron) and Hur are with you—any leader judging matters requiring more wisdom can approach them for help.”

15 Then Mosheh went to the base of the mountain and a cloud covered over it. 16 Yahweh’s radiance settled on Mt. Sinay, and the cloud covered it for six days, then on the seventh day he called to Mosheh from within the cloud. 17 The appearance of Yahweh’s radiance was like a roaring fire on the top of the mountain from what the Israelis below could see. 18 Then Mosheh entered into the cloud and continued up the mountain, and he remained up there for forty full days.[ref]
