Leviticus 5:14-16

¹⁴Yahweh also said to Moses/me,

¹⁵“When you sin, without intending to, by not giving to Yahweh the things that you are required to give to him, you must pay a penalty by bringing to Yahweh a ram that has no defects. You must determine how much silver it is worth, by using the official standard in the temple. It will be an offering to cause you to no longer be guilty.

¹⁶But you must also make restitution for what you failed to give to Yahweh, adding one-fifth of its value. You must give that to the priest. He will offer the ram as a sacrifice for the sin that you have committed, and cause you to no longer be guilty; and you will be forgiven.
