Exodus 19:16-25 World English Bible (WEB)
16 On the third day, when it was morning, there were thunders and lightnings, and a thick cloud on the mountain, and the sound of an exceedingly loud trumpet; and all the people who were in the camp trembled. 17 Moses led the people out of the camp to meet God; and they stood at the lower part of the mountain. 18 All of Mount Sinai smoked, because Yahweh descended on it in fire; and its smoke ascended like the smoke of a furnace, and the whole mountain quaked greatly. 19 When the sound of the trumpet grew louder and louder, Moses spoke, and God answered him by a voice. 20 Yahweh came down on Mount Sinai, to the top of the mountain. Yahweh called Moses to the top of the mountain, and Moses went up.
21 Yahweh said to Moses, “Go down, warn the people, lest they break through to Yahweh to gaze, and many of them perish. 22 Let the priests also, who come near to Yahweh, sanctify themselves, lest Yahweh break out on them.”
23 Moses said to Yahweh, “The people can’t come up to Mount Sinai, for you warned us, saying, ‘Set bounds around the mountain, and sanctify it.’”
24 Yahweh said to him, “Go down! You shall bring Aaron up with you, but don’t let the priests and the people break through to come up to Yahweh, lest he break out against them.”
25 So Moses went down to the people, and told them.
Exodus 19:16-25 New International Version (NIV)
16 On the morning of the third day there was thunder and lightning, with a thick cloud over the mountain, and a very loud trumpet blast. Everyone in the camp trembled. 17 Then Moses led the people out of the camp to meet with God, and they stood at the foot of the mountain. 18 Mount Sinai was covered with smoke, because the Lord descended on it in fire. The smoke billowed up from it like smoke from a furnace, and the whole mountain[a] trembled violently. 19 As the sound of the trumpet grew louder and louder, Moses spoke and the voice of God answered him.[b]
20 The Lord descended to the top of Mount Sinai and called Moses to the top of the mountain. So Moses went up 21 and the Lord said to him, “Go down and warn the people so they do not force their way through to see the Lord and many of them perish. 22 Even the priests, who approach the Lord, must consecrate themselves, or the Lord will break out against them.”
23 Moses said to the Lord, “The people cannot come up Mount Sinai, because you yourself warned us, ‘Put limits around the mountain and set it apart as holy.’”
24 The Lord replied, “Go down and bring Aaron up with you. But the priests and the people must not force their way through to come up to the Lord, or he will break out against them.”
25 So Moses went down to the people and told them.
