Exodus 19:5-8

5Now if you obey me fully and keep my covenant, then out of all nations you will be my treasured possession. Although the whole earth is mine,

6you will be for me a kingdom of priests and a holy nation.’ These are the words you are to speak to the Israelites.”

7So Moses went back and summoned the elders of the people and set before them all the words the Lord had commanded him to speak.

8The people all responded together, “We will do everything the Lord has said.” So Moses brought their answer back to the Lord.
