Leviticus 27:7-9

New Revised Standard Version, Anglicised

⁷ And if the person is sixty years old or over, then the equivalent for a male is fifteen shekels, and for a female ten shekels. ⁸ If any cannot afford the equivalent, they shall be brought before the priest and the priest shall assess them; the priest shall assess them according to what each one making a vow can afford.

⁹ If it concerns an animal that may be brought as an offering to the Lord, any such that may be given to the Lord shall be holy.
