Exodus 19:1-9 New American Standard Bible (NASB)

Moses on Sinai

19 In the third month after the sons of Israel had gone out of the land of Egypt, ^[a]on that very day they came into the wilderness of Sinai. ² When they set out from Rephidim, they came to the wilderness of Sinai and camped in the wilderness; and there Israel camped in front of the mountain. ³ And Moses went up to God, and the Lord called to him from the mountain, saying, “This is what you shall say to the house of Jacob and tell the sons of Israel: ⁴ ‘You yourselves have seen what I did to the Egyptians, and how I carried you on eagles’ wings, and brought you to Myself. ⁵ Now then, if you will indeed obey My voice and keep My covenant, then you shall be My ^[b]own possession among all the peoples, for all the earth is Mine; ⁶ and you shall be to Me a kingdom of priests and a holy nation.’ These are the words that you shall speak to the sons of Israel.”

⁷ So Moses came and called the elders of the people, and set before them all these words which the Lord had commanded him. ⁸ Then all the people answered together and said, “All that the Lord has spoken we will do!” And Moses brought back the words of the people to the Lord. ⁹ Then the Lord said to Moses, “Behold, I will come to you in a thick cloud, so that the people may hear when I speak with you and may also trust in you forever.” Then Moses told the words of the people to the Lord.

Exodus 19:16-22 New American Standard Bible (NASB)

¹⁶ So it came about on the third day, when it was morning, that there were ^[a]thunder and lightning flashes and a thick cloud over the mountain and a very loud trumpet sound, so that all the people who were in the camp trembled. ¹⁷ And Moses brought the people out of the camp to meet God, and they stood at the ^[b]foot of the mountain.

The Lord Visits Sinai

¹⁸ Now Mount Sinai was all in smoke because the Lord descended upon it in fire; and its smoke ascended like the smoke of a furnace, and the entire mountain ^[c]quaked violently. ¹⁹ When the sound of the trumpet grew louder and louder, Moses spoke, and God answered him with ^[d]thunder. ²⁰ Then the Lord came down on Mount Sinai, to the top of the mountain; and the Lord called Moses to the top of the mountain, and Moses went up. ²¹ Then the Lord spoke to Moses: “Go down, ^[e]warn the people, so that they do not break through to the Lord to stare, and many of them ^[f]perish. ²² Also have the priests who approach the Lord consecrate themselves, or else the Lord will break out against them.”
