Leviticus Chapter 27 World English Bible
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.
He shall not alter it, nor change it, a good for a bad, or a bad for a good: and if he shall at all change animal for animal, then both it and that for which it is changed shall be holy.
"'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.
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 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.
"'Notwithstanding, no devoted thing, that a man shall devote to Yahweh of all that he has, whether of man or animal, or of the field of his possession, shall be sold or redeemed: every devoted thing is most holy to Yahweh.
He shall not search whether it is good or bad, neither shall he change it: and if he changes it at all, then both it and that for which it is changed shall be holy. It shall not be redeemed.'"
