3your 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.

4If she is a female, then your valuation shall be thirty shekels.

5If 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.

6If 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.
