Leviticus 27:1-8

Laws About Vows

1The Lord spoke to Moses, saying, 2Speak to the people of Israel and say to them, If anyone amakes a special vow to the Lord involving the valuation of persons, 3then the valuation of a male from twenty years old up to sixty years old shall be fifty shekels
A  shekel was about 2/5 ounce or 11 grams
of silver, according to the cshekel of the sanctuary.
4If the person is a female, the valuation shall be thirty shekels. 5If the person is from five years old up to twenty years old, the valuation shall be for a male twenty shekels, and for a female ten shekels. 6If the person is from a month old up to five years old, the valuation shall be for a male five shekels of silver, and for a female the valuation shall be three shekels of silver. 7And if the person is sixty years old or over, then the valuation for a male shall be fifteen shekels, and for a female ten shekels. 8And if someone is too poor to pay the valuation, then he shall be made to stand before the priest, and the priest shall value him; the priest shall value him according to what the vower can afford.
