NET Bible
"Then the LORD spoke to Moses:"
— Numbers 3:44, NET Bible
And take the Levites for me– I am the LORD– instead of all the firstborn males among the Israelites, and the livestock of the Levites instead of all the firstborn of the livestock of the Israelites.”
So Moses numbered all the firstborn males among the Israelites, as the LORD had commanded him.
And all the firstborn males, by the number of the names from a month old and upward, totaled 22,273.
Then the LORD spoke to Moses:
“Take the Levites instead of all the firstborn males among the Israelites, and the livestock of the Levites instead of their livestock. And the Levites will be mine. I am the LORD.
And for the redemption of the 273 firstborn males of the Israelites who exceed the number of the Levites,
collect five shekels for each one individually; you are to collect this amount in the currency of the sanctuary shekel(this shekel is twenty gerahs).
