Exodus 19:3-8

3Moses went up to God [on the mountain], and the Lord called to him from the mountain, saying, “Say this to the house of Jacob and tell the Israelites:

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

5Now therefore, if you will in fact obey My voice and keep My covenant (agreement), then you shall be My own special possession and treasure from among all peoples [of the world], for all the earth is Mine;

6and you shall be to Me a kingdom of priests and a holy nation [set apart for My purpose].’ These are the words that you shall speak to the Israelites.”

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

8All the people answered together and said, “We will do everything that the Lord has spoken.” And Moses reported the words of the people to the Lord.
