"I have taken the Levites from among the People of Israel as a stand-in for every Israelite mother's firstborn son. The Levites belong to me.
13
All the firstborn are mine - when I killed all the firstborn in Egypt, I consecrated for my own use every firstborn in Israel, whether human or animal. They belong to me. I am God."

God spoke to Moses in the Wilderness of Sinai:

"Count the Levites by their ancestral families and clans. Count every male a month old and older."
16
Moses counted them just as he was instructed by the mouth of God.
