Leviticus 5:14-16

Then the LORD said to Moses, “If one of you commits a sin by unintentionally defiling the LORD’s sacred property, you must bring a guilt offering to the LORD. The offering must be your own ram with no defects, or you may buy one of equal value with silver, as measured by the weight of the sanctuary shekel. You must make restitution for the sacred property you have harmed by paying for the loss, plus an additional 20 percent. When you give the payment to the priest, he will purify you with the ram sacrificed as a guilt offering, making you right with the LORD, and you will be forgiven.
