Exodus 19:3-8

3And Moses went up to God, and the Lord called to him from the mountain, saying, “Thus you shall say to the house of Jacob, and tell the children of Israel:

4‘You have seen what I did to the Egyptians, and how I bore you on eagles’ wings and brought you to Myself.

5Now therefore, if you will indeed obey My voice and keep My covenant, then you shall be a special treasure to Me above all people; for all the earth is Mine.

6And you shall be to Me a kingdom of priests and a holy nation.’ These are the words which you shall speak to the children of Israel.”

7So Moses came and called for the elders of the people, and laid before them all these words which the Lord commanded him.

8Then all the people answered together and said, “All that the Lord has spoken we will do.” So Moses brought back the words of the people to the Lord.
