Exodus 19:5-6 AMPC
Now therefore, if you will obey My voice in truth and keep My covenant, then you shall be My own peculiar possession and treasure from among and above all peoples; for all the earth is Mine.
And you shall be to Me a kingdom of priests, a holy nation [consecrated, set apart to the worship of God]. These are the words you shall speak to the Israelites.
