NASB
""For all the firstborn are Mine; on the day that I struck down all the firstborn in the land of Egypt, I sanctified to Myself all the firstborn in Israel, from man to beast. They shall be Mine; I am the LORD.""
— Numbers 3:13, NASB
“Because all the firstborn are mine; for on the day that I smote all the firstborn in the land of Egypt I hallowed unto me all the firstborn in Israel, both man and beast: mine shall they be: I am the Lord.”
“for all the first-born are mine; on the day that I smote all the first-born in the land of Egypt I hallowed unto me all the first-born in Israel, both man and beast; mine they shall be: I am Jehovah. ”
“for all the firstborn are mine. On the day that I struck down all the firstborn in the land of Egypt I made holy to me all the firstborn in Israel, both man and animal. They shall be mine. I am Yahweh."”
“because all the firstborn are mine. When I destroyed all the firstborn in the land of Egypt, I set apart for myself all the firstborn in Israel, both man and beast. They belong to me. I am the LORD.””
“For every firstborn is mine: since I struck the firstborn in the land of Egypt: I have sanctified to myself whatsoever is firstborn in Israel both of man and beast, they are mine: I am the Lord.”
“For all the first sons are mine; on the day when I put to death all the first sons in the land of Egypt, I took for myself every first male birth of man and beast. They are mine; I am the Lord.”
“Because all the firstborn are mine; for on the day that I smote all the firstborn in the land of Egypt I hallowed unto me all the firstborn in Israel, both man and beast: mine shall they be: I am the Lord.”
"So you shall appoint Aaron and his sons that they may keep their priesthood, but the layman who comes near shall be put to death."
Again the LORD spoke to Moses, saying,
"Now, behold, I have taken the Levites from among the sons of Israel instead of every firstborn, the first issue of the womb among the sons of Israel. So the Levites shall be Mine.
"For all the firstborn are Mine; on the day that I struck down all the firstborn in the land of Egypt, I sanctified to Myself all the firstborn in Israel, from man to beast. They shall be Mine; I am the LORD."
Then the LORD spoke to Moses in the wilderness of Sinai, saying,
"Number the sons of Levi by their fathers' households, by their families; every male from a month old and upward you shall number."
So Moses numbered them according to the word of the LORD, just as he had been commanded.
