Leviticus 27:25-27

New King James Version

²⁵ And all your valuations shall be according to the shekel of the sanctuary: ^(A)twenty gerahs to the shekel.

²⁶ ‘But the ^(B)firstborn of the animals, which should be the Lord’s firstborn, no man shall dedicate; whether it is an ox or sheep, it is the Lord’s. ²⁷ And if it is an unclean animal, then he shall redeem it according to your valuation, and ^(C)shall add one-fifth to it; or if it is not redeemed, then it shall be sold according to your valuation.
