Exodus 19:4

2When they had departed from Rephidim, and had come to the wilderness of Sinai, they encamped in the wilderness; and there Israel encamped before the mountain.

3Moses went up to God, and the LORD called to him out of the mountain, saying, “This is what you shall tell the house of Jacob, and tell the children of Israel:

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

5Now therefore, if you will indeed obey my voice and keep my covenant, then you shall be my own possession from 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 which you shall speak to the children of Israel.”
