Numbers 3:40-43

LITV(i) 40 And Jehovah said to Moses, Count every first-born male of the sons of Israel from a son of a month and upward, and take the number of their names. 41 And you shall take the Levites for Me, I am Jehovah, instead of every first-born among the sons of Israel; and the cattle of the Levites instead of every firstling among the livestock of the sons of Israel. 42 And Moses numbered as Jehovah commanded him, all the first-born among the sons of Israel. 43 And all the first-born males according to the number of names, from a son of a month and upward, of those numbered of them were twenty two thousand, two hundred and seventy three.
