You must not try to put another animal in its place. You must not try to change it for something else. You must not try to change a good animal for a bad animal. You must not change a bad animal for a good animal. If you do try to change animals, both animals will become holy—both animals will belong to the Lord.
"Some animals cannot be offered as sacrifices to the Lord. If you bring one of these unclean animals to the Lord, that animal must be brought to the priest.
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.
"You might dedicate a field to God. The value of this field will depend on how much seed is needed to plant it. It will be 50 shekels of silver for each homer of barley seed.
But if you give your field after the Jubilee, the priest must decide its exact price. He must count the number of years to the next year of Jubilee and use that number to decide the price.
If you don't buy the land back by the year of Jubilee, the field will remain holy to the Lord—it will belong to the priest forever. It will be treated like any other thing that was given completely to the Lord.
"You can give cattle and sheep as special gifts to the Lord. But if the animal is the firstborn, it already belongs to the Lord. So you cannot give these animals as special gifts.
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.
"There is a special kind of gift that people give to the Lord. It belongs only to him, and it cannot be bought back or sold. This gift belongs to the Lord. This type of gift includes people, animals, and fields from the family property.
The owner should not worry if the chosen animal is good or bad or change the animal for another animal. If this happens, both animals will belong to the Lord. That animal cannot be bought back."
