Leviticus 27:2-7

2‘Speak to Israel's people. Tell them this. A person might give another person to the Lord for a special promise.

3They can make that person free. But they must give the right amount of money to God. For a man between 20 years and 60 years old, they must give 50 pieces of silver.

4For a woman, they must give 30 pieces of silver.

5For a male between five years and 20 years old, they must give to God 20 pieces of silver. For a female, they must give ten pieces of silver.

6For a boy between one month and five years old, they must give five pieces of silver. For a girl of the same age, God must have three pieces of silver.

7If a man is older than 60 years, they must give 15 pieces of silver. For a woman, they must give ten pieces of silver.
