TSK · Leviticus 22:14

“When a person commits a trespass and sins by straying unintentionally from the regulations about the LORD’s holy things, then he must bring his penalty for guilt to the LORD, a flawless ram from the flock, convertible into silver shekels according to the standard of the sanctuary shekel, for a guilt offering.

If, however, the person who made the vow redeems the animal, he must add one fifth to its conversion value.
