⁴⁴ Then the Lord spoke to Moses, saying, ⁴⁵ “Take the Levites as substitutes for all the firstborn among the Israelites and the livestock of the Levites as substitutes for their livestock, and the Levites shall be mine. I am the Lord.^{(A) 46} As the price of redemption of the two hundred seventy-three of the firstborn of the Israelites, over and above the number of the Levites,^{(B) 47} you shall take five shekels apiece, reckoning by the shekel of the sanctuary, a shekel of twenty gerahs.^{(C) 48} Give to Aaron and his sons the money by which the excess number of them is redeemed.”
