Leviticus 27:7-9

Amplified Bible, Classic Edition

⁷ And if the person is from sixty years old and above, if it be a male, then your valuation shall be fifteen shekels and for the female ten shekels.

⁸ But if the man is too poor to pay your valuation, then he shall be set before the priest, and the priest shall value him; according to the ability of him who vowed shall the priest value him.

⁹ If it is a beast of which men offer an offering to the Lord, all that any man gives of such to the Lord shall be holy.
