16 On the third day in the morning there was thunder and lightning and a dense cloud on the mountain, and the sound of a very loud horn; all the people who were in the camp trembled. 17 Moses brought the people out of the camp to meet God, and they took their place at the foot of the mountain. 18 Now Mount Sinai was completely covered with smoke because the Lord had descended on it in fire, and its smoke went up like the smoke of a great furnace, and the whole mountain shook violently. 19 When the sound of the horn grew louder and louder, Moses was speaking and God was answering him with a voice. 20 The Lord came down on Mount Sinai, on the top of the mountain, and the Lord summoned Moses to the top of the mountain, and Moses went up.

1 A psalm by Asaph. El, God, the Lord has spoken, and summoned the earth to come from the east and west. 2 From Zion, the most beautiful of all places, God has come in splendor. 3 “May our God come and not be silent.” Consuming fire goes ahead of him, and all around him a storm rages. 4 He summons the heavens above, as well as the earth, so that he might judge his people. 5 He says: “Assemble my covenant people before me, those who ratified a covenant with me by sacrifice.”
