Leviticus 27:7-9

American Standard Version

⁷ And if it be from sixty years old and upward; if it be a male, then thy estimation shall be fifteen shekels, and for the female ten shekels. ⁸ But if he be poorer than thy estimation, then he shall be set before the priest, and the priest shall value him; according to the ability of him that vowed shall the priest value him.

⁹ And if it be a beast, whereof men offer an oblation unto Jehovah, all that any man giveth of such unto Jehovah shall be holy.
