How does someone sin unintentionally?


“Say to the Israelites: ‘When anyone sins unintentionally and does what is forbidden in any of the Lord’s commands…’” Leviticus 4:2
“‘If the whole Israelite community sins unintentionally and does what is forbidden in any of the Lord’s commands, even though the community is unaware of the matter, when they realize their guilt and the sin they committed becomes known, the assembly must bring a young bull as a sin offering and present it before the tent of meeting.’” Leviticus 4:13-14
            In these passages, God focused more on the intent of the sin.  The person didn’t wake up thinking about blaspheming the Lord or hitting that person in the face, but suddenly it happened.  Kind of like “involuntary manslaughter.”
            Or, the person committed a sin not really knowing what he or she did, or the impact of that sin.  For example, if someone seduces a woman then finds out she was married.  There was a sin, but a greater sin happened too.
            All sin is sin, but some sin is not premediated or intentional and God was covering the consequences of those sins with an offering.  This included an individual and an entire community.  It was a guarantee that someone’s sins were all covered, the known and the unknown trespasses.
