Leviticus 5:3, 6, 17

“Or suppose you unknowingly touch something that makes a person unclean. When you realize what you have done, you must admit your guilt.

Then you must bring to the LORD as the penalty for your sin a female from the flock, either a sheep or a goat. This is a sin offering with which the priest will purify you from your sin, making you right with the LORD.

“Suppose you sin by violating one of the LORD’s commands. Even if you are unaware of what you have done, you are guilty and will be punished for your sin.
