Leviticus 27:1-8, 22-25

GOD spoke to Moses: He said, “Speak to the People of Israel. Tell them, If anyone wants to vow the value of a person to the service of GOD, set the value of a man between the ages of twenty and sixty at fifty shekels of silver, according to the Sanctuary shekel. For a woman the valuation is thirty shekels. If the person is between the ages of five and twenty, set the value at twenty shekels for a male and ten shekels for a female. If the person is between one month and five years, set the value at five shekels of silver for a boy and three shekels of silver for a girl. If the person is over sixty, set the value at fifteen shekels for a man and ten shekels for a woman. If anyone is too poor to pay the stated amount, he is to present the person to the priest, who will then set the value for him according to what the person making the vow can afford.

“If a man dedicates to GOD a field he has bought, a field which is not part of the family land, the priest will compute its proportionate value in relation to the next year of Jubilee. The man must pay its value on the spot as something that is now holy to GOD, belonging to the Sanctuary. In the year of Jubilee it goes back to its original owner, the man from whom he bought it. The valuations will be reckoned by the Sanctuary shekel, at twenty gerahs to the shekel.
