Exodus 19:5-8

5Now therefore, if you will indeed obey my voice and keep my covenant, you shall be my treasured possession among all peoples, for all the earth is mine;

6and you shall be to me a kingdom of priests and a holy nation.' These are the words that you shall speak to the people of Israel."

7So Moses came and called the elders of the people and set before them all these words that the Lord had commanded him.

8All the people answered together and said, "All that the Lord has spoken we will do." And Moses reported the words of the people to the Lord.
