Leviticus 4:1-3 New International Version (NIV)
The Sin Offering
4 The Lord said to Moses, 2 “Say to the Israelites: ‘When anyone sins unintentionally and does what is forbidden in any of the Lord’s commands—
3 “‘If the anointed priest sins, bringing guilt on the people, he must bring to the Lord a young bull without defect as a sin offering for the sin he has committed.
Have you ever done something wrong and not realize it until later? Even unintentional sin is sin. God’s commands helped the Israelites be aware of their known sin and unintentional sin. When you sin, ask for forgiveness and change your behavior. God forgives. The death of Jesus was the final sin offering.
