You must not put any other animal in its place. Don’t try to trade a good animal for a bad one or a bad animal for a good one. If you try to change animals, both animals will become holy—they will both belong to the Lord.
You must give what you promised and add one-fifth of that amount as a fine. Give it to the priest and he will use the ram to make you pure, and God will forgive you.
The priest will decide a price for that animal. It doesn’t make any difference if the animal is good or bad. If the priest decides on a price, that is the price for the animal.
“If you dedicate your house as holy to the Lord, the priest must decide its price. It doesn’t make any difference if the house is good or bad. If the priest decides on a price, that is the price for the house.
If the firstborn animal is an unclean animal, you must buy back that animal. The priest will decide the price of the animal, and you must add one-fifth to that price. If you don’t buy that animal back, the priest will sell the animal for whatever price he decides.
