Leviticus 27:2-8

2“Speak to the Israelites and tell them: When someone makes a special vow to the Lord that involves the assessment of people,

3if the assessment concerns a male from twenty to sixty years old, your assessment is fifty silver shekels measured by the standard sanctuary shekel.

4If the person is a female, your assessment is thirty shekels.

5If the person is from five to twenty years old, your assessment for a male is twenty shekels and for a female ten shekels.

6If the person is from one month to five years old, your assessment for a male is five silver shekels, and for a female your assessment is three shekels of silver.

7If the person is sixty years or more, your assessment is fifteen shekels for a male and ten shekels for a female.

8But if one is too poor to pay the assessment, he is to present the person before the priest and the priest will set a value for him. The priest will set a value for him according to what the one making the vow can afford.
