MKJV(i)
40 And Jehovah said to Moses, Number all the first-born of the males of the sons of Israel from a month old and upward, and take the number of their names.
41 You shall take the Levites for Me, I am Jehovah, in the place of all the first-born among the sons of Israel; and the cattle of the Levites instead of all the firstlings among the cattle of the sons of Israel.
