Leviticus 27:6-8

American Standard Version

⁶ And if it be from a month old even unto five years old, then thy estimation shall be of the male five shekels of silver, and for the female thy estimation shall be three shekels of silver. 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.
