Exodus 19:5-8

5And now, if you will diligently listen to me and keep my covenant, then you will be my special possession out of all the nations, for all the earth is mine,

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

7So Moses came and summoned the elders of Israel. He set before them all these words that the Lord had commanded him,

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