Leviticus 27:25-27

New American Standard Bible

²⁵ Every assessment of yours, moreover, shall be by ^(A)the shekel of the sanctuary. The shekel shall be twenty gerahs.

²⁶ ‘^(B)However, a firstborn among animals, which as a firstborn belongs to the Lord, no one may consecrate; whether ox or sheep, it is the Lord’s. ²⁷ But if it is among the unclean animals, then he shall ^[a]redeem it according to your assessment and add to it a fifth of it; and if it is not redeemed, then it shall be sold according to your assessment.
