Leviticus 27:7-9

Christian Standard Bible

⁷ If the person is sixty years or more, your assessment is fifteen shekels for a male and ten shekels for a female. ⁸ But if one is too poor to pay the assessment, he is to present the person before the priest and the priest will set a value for him. The priest will set a value for him according to what the one making the vow can afford.

⁹ “If the vow involves one of the animals that may be brought as an offering to the Lord, any of these he gives to the Lord will be holy.
