'Valuation' in the Bible
"Speak to the children of Israel, and say to them, 'When a man makes a vow, the persons shall be for Yahweh by your valuation.
Your valuation shall be of a male from twenty years old even to sixty years old, even your valuation shall be fifty shekels of silver, after the shekel of the sanctuary.
If it is a female, then your valuation shall be thirty shekels.
If the person is from five years old even 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 even 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 it is a male, then your valuation shall be fifteen shekels, and for a female ten shekels.
But if he is poorer than your valuation, then he shall be set before the priest, and the priest shall value him; according to the ability of him who vowed shall the priest value him.
But if he will indeed redeem it, then he shall add the fifth part of it to its valuation.
If he who dedicates it will redeem his house, then he shall add the fifth part of the money of your valuation to it, and it shall be his.
"'If a man dedicates to Yahweh part of the field of his possession, then your valuation shall be according to the seed for it: the sowing of a homer of barley shall be valued at fifty shekels of silver.
If he dedicates his field from the Year of Jubilee, according to your valuation it shall stand.
But if he dedicates his field after the Jubilee, then the priest shall reckon to him the money according to the years that remain to the Year of Jubilee; and an abatement shall be made from your valuation.
If he who dedicated the field will indeed redeem it, then he shall add the fifth part of the money of your valuation to it, and it shall remain his.
then the priest shall reckon to him the worth of your valuation up to the Year of Jubilee; and he shall give your valuation on that day, as a holy thing to Yahweh.
If it is an unclean animal, then he shall buy it back according to your valuation, and shall add to it the fifth part of it: or if it isn't redeemed, then it shall be sold according to your valuation.
