TSK · Leviticus 27:13

then it shall be, if he has sinned, and is guilty, he shall restore that which he took by robbery, or the thing which he has gotten by oppression, or the deposit which was committed to him, or the lost thing which he found,

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 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.
