The Redemption of the Firstborn

40 Then the Lord said to Moses: Enroll all the firstborn males of the Israelites, from a month old and upward, and count their names. 41 But you shall accept the Levites for me—I am the Lord—as substitutes for all the firstborn among the Israelites, and the livestock of the Levites as substitutes for all the firstborn among the livestock of the Israelites. 42 So Moses enrolled all the firstborn among the Israelites, as the Lord commanded him. 43 The total enrollment, all the firstborn males from a month old and upward, counting the number of names, was twenty-two thousand two hundred seventy-three.

44 Then the Lord spoke to Moses, saying: 45 Accept 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. 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, 47 you shall accept five shekels apiece, reckoning by the shekel of the sanctuary, a shekel of twenty gerahs. 48 Give to Aaron and his sons the money by which the excess number of them is redeemed.
