Leviticus 27:25-27

Revised Standard Version Catholic Edition

²⁵ Every valuation shall be according to the shekel of the sanctuary: twenty gerahs shall make a shekel.

²⁶ “But a firstling of animals, which as a firstling belongs to the Lord, no man may dedicate; whether ox or sheep, it is the Lord’s. ²⁷ And if it is an unclean animal, then he shall buy it back at your valuation, and add a fifth to it; or, if it is not redeemed, it shall be sold at your valuation.
