44 And the LORD spoke to Moses, saying,

45 Take the Levites instead of all the firstborn among the children of Israel, and the cattle of the Levites instead of their cattle; and the Levites shall be mine: I am the LORD.

46 And for those that are to be redeemed of the two hundred and three score and thirteen of the firstborn of the children of Israel, which are more than the Levites;

47 You shall even take five shekels apiece by the poll, after the shekel of the sanctuary shall you take them: (the shekel is twenty gerahs:)

48 And you shall give the money, with which the odd number of them is to be redeemed, to Aaron and to his sons.
