So Moses had all the first sons among the children of Israel numbered, as the Lord said to him.
And give to me the Levites I am the Lord in place of the first sons of the children of Israel; and the cattle of the Levites in place of the first births among the cattle of the children of Israel.
Every first son from a month old and over was numbered by name, and the number came to twenty-two thousand, two hundred and seventy-three.
