'I Am the Lord' in the Bible

for all the firstborn are Mine. On the day that I killed all the firstborn in the land of Egypt, I consecrated for Myself all the firstborn in Israel, both man and animal. They shall be mine; I am the Lord.”

You shall take the Levites for Me instead of and as a substitute for all the firstborn among the Israelites. I am the Lord; and you shall take the cattle of the Levites instead of and as a substitute for all the firstborn among the cattle of the Israelites.”

“Take the Levites [for Me] instead of all the firstborn among the sons of Israel, and the cattle of the Levites instead of their cattle. And the Levites shall be Mine. I am the Lord.

Also in the day of rejoicing, and in your appointed feasts, and at the beginnings of your months, you shall sound the trumpets over your burnt offerings, and over the sacrifice of your peace offerings; and they shall be as a reminder of you before your God. I am the Lord your God.”

I am the Lord your God, who brought you out of the land of Egypt to be your God. I am the Lord your God.”
