And if a soul sin, and commit any of these things which are forbid-den to be done by the command-ments of the LORD; though he wist it not, yet is he guilty, and shall bear his iniquity.
Leviticus 5:17
In the seventh month, on the tenth day of the month, you shall afflict your souls, and you shall not do any work ... For on that day he shall provide atonement for you to cleanse you from all your sins before YHWH. -Leviticus 16:29-30
