Leviticus 27:2-7

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.
