Leviticus 27:2-8

2“Speak to the Israelites and tell them, ‘When a man makes a special votive offering based on the conversion value of persons to the Lord,

3the conversion value of the male from twenty years old up to sixty years old is fifty shekels by the standard of the sanctuary shekel.

4If the person is a female, the conversion value is thirty shekels.

5If the person is from five years old up to twenty years old, the conversion value of the male is twenty shekels, and for the female ten shekels.

6If the person is one month old up to five years old, the conversion value of the male is five shekels of silver, and for the female the conversion value is three shekels of silver.

7If the person is from sixty years old and older, if he is a male the conversion value is fifteen shekels, and for the female ten shekels.

8If he is too poor to pay the conversion value, he must stand the person before the priest and the priest will establish his conversion value; according to what the man who made the vow can afford, the priest will establish his conversion value.
