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 she is a female, then your valuation shall be thirty shekels.
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.
