Leviticus 27:2-13

²“Speak to the children of Israel, and say to them, ‘When a man consecrates a person to Yahweh in a vow, according to your valuation,

³your valuation of a male from twenty years old to sixty years old shall be fifty shekels of silver, according to the shekel of the sanctuary.

⁴If she is a female, then your valuation shall be thirty shekels.

⁵If the person is from five years old to twenty years old, then your valuation shall be for a male twenty shekels, and for a female ten shekels.

⁶If the person is from a month old to five years old, then your valuation shall be for a male five shekels of silver, and for a female your valuation shall be three shekels of silver.

⁷If the person is from sixty years old and upward; if he is a male, then your valuation shall be fifteen shekels, and for a female ten shekels.

⁸But if he is poorer than your valuation, then he shall be set before the priest, and the priest shall assign a value to him. The priest shall assign a value according to his ability to pay.

⁹“‘If it is an animal of which men offer an offering to Yahweh, all that any man gives of such to Yahweh becomes holy.

¹⁰He shall not alter it, nor exchange it, a good for a bad, or a bad for a good. If he shall at all exchange animal for animal, then both it and that for which it is exchanged shall be holy.

¹¹If it is any unclean animal, of which they do not offer as an offering to Yahweh, then he shall set the animal before the priest;

¹²and the priest shall evaluate it, whether it is good or bad. As the priest evaluates it, so it shall be.

¹³But if he will indeed redeem it, then he shall add the fifth part of it to its valuation.
