Leviticus 27:2–8

²Speak unto the children of Israel and say unto them, When any one devoteth anything by a vow, the persons shall be for Jehovah according to thy valuation. ³And thy valuation shall be of the male from twenty years old even unto sixty years old: thy valuation shall be fifty shekels of silver, after the shekel of the sanctuary; ⁴and if it be of a female, thy valuation shall be thirty shekels. ⁵And if it be from five years old even unto twenty years old, thy valuation of the male shall be twenty shekels, and for the female ten shekels. ⁶And if it be from a month old even unto five years old, thy valuation of the male shall be five shekels of silver; and for the female thy valuation shall be three shekels of silver. ⁷And if it be from sixty years old and above, if it be a male, thy valuation shall be fifteen shekels; and for the female ten shekels. ⁸And if he be poorer than thy valuation, he shall present himself before the priest, and the priest shall value him: according to his means that vowed shall the priest value him.
