Leviticus 27:2-8

2“Speak to the sons of Israel and say to them, ‘1When a man makes a difficult vow, he shall be valued according to your valuation of persons belonging to the Lord. 3If your valuation is of the male from twenty years even to sixty years old, then your valuation shall be fifty shekels of silver, after 2the shekel of the sanctuary. 4Or if it is a female, then your valuation shall be thirty shekels. 5If it be from five years even to twenty years old then your valuation for the male shall be twenty shekels and for the female ten shekels. 6But if they are from a month even up to five years old, then your valuation shall be 3five shekels of silver for the male, and for the female your valuation shall be three shekels of silver. 7If they are from sixty years old and upward, if it is a male, then your valuation shall be fifteen shekels, and for the female ten shekels. 8But if he is poorer than your valuation, then he shall be placed before the priest and the priest shall value him; 4according to 5the means of the one who vowed, the priest shall value him.
