8If anyone making the vow is too poor to pay the specified amount, the person being dedicated is to be presented to the priest, who will set the value according to what the one making the vow can afford.
10They must not exchange it or substitute a good one for a bad one, or a bad one for a good one; if they should substitute one animal for another, both it and the substitute become holy.
11If what they vowed is a ceremonially unclean animal--one that is not acceptable as an offering to the LORD--the animal must be presented to the priest,
14"'If anyone dedicates their house as something holy to the LORD, the priest will judge its quality as good or bad. Whatever value the priest then sets, so it will remain.
16"'If anyone dedicates to the LORD part of their family land, its value is to be set according to the amount of seed required for it--fifty shekels of silver to a homer of barley seed.
18But if they dedicate a field after the Jubilee, the priest will determine the value according to the number of years that remain until the next Year of Jubilee, and its set value will be reduced.
26"'No one, however, may dedicate the firstborn of an animal, since the firstborn already belongs to the LORD; whether an ox or a sheep, it is the LORD's.
27If it is one of the unclean animals, it may be bought back at its set value, adding a fifth of the value to it. If it is not redeemed, it is to be sold at its set value.
28"'But nothing that a person owns and devotes to the LORD--whether a human being or an animal or family land--may be sold or redeemed; everything so devoted is most holy to the LORD.
33No one may pick out the good from the bad or make any substitution. If anyone does make a substitution, both the animal and its substitute become holy and cannot be redeemed.'"
