He shall not exchange it nor substitute it, good for bad or bad for good. If he in fact substitutes an animal for another, then both it and its substitute shall be holy.
When a man consecrates his house as holy to the Lord, then the priest shall set its value, whether good or bad, according to the equivalent value set by the priest, so shall it be established.
If it is among the unclean animals, then he shall ransom it at the equivalent value and shall add one-fifth to it, but if it is not redeemed, then it shall be sold at the equivalent value.
And he shall repay the sin that he committed with regard to the holy thing and shall add one-fifth to it and give it to the priest. The priest shall make atonement for him with the ram of the guilt offering, and he shall be forgiven.
