Leviticus 27:4

The LORD spoke to Moses, saying,

“Speak to the children of Israel, and say to them, ‘When a man consecrates a person to the LORD in a vow, according to your valuation,

your valuation of a male from twenty years old to sixty years old shall be fifty shekels of silver, according to the shekel of the sanctuary.

If the person is from five years old to twenty years old, then your valuation shall be for a male twenty shekels, and for a female ten shekels.

If the person is from a month old to five years old, then your valuation shall be for a male five shekels of silver, and for a female your valuation shall be three shekels of silver.

If the person is from sixty years old and upward; if he is a male, then your valuation shall be fifteen shekels, and for a female ten shekels.
