Bible Notes Online - Leviticus 4 - ESV
Commentary

The sin offering was a sacrifice for sin. This deals with the sin nature in the offender, which produces unintentional acts of sin (v2, 13, 22, 27). This offering was always included in the Jewish feasts, since each individual required to have his wrong-doing atoned for.

While the trespass offering (ch5) deals with individual acts of sin and uncleanness, ie: the offence. Such is the scope of Christ' s death, to which this points, that all our sins and unrighteousness are dealt with.

What is not included here is a sacrifice for deliberate acts of sin. Those who are part of the community of God do not do such things.

v1 Alfred Edersheim says that the sin offering; 'represented a terrible necessity for which Gods, in His wondrous grace, had made provision.’ (The Temple, its Minstry and Service)

v2: The offering is for the individual, even the anointed priest (v3), the whole community (v13), a leader (v22), and any member of the community (v27).

v3: The man with defect had to bring an animal without defect; v23, 28, 32. The sinner has to trust solely in Jesus Christ, the only one without defect. Defect in us is defined strictly, in relation to ANY of the Lord's commands (v2, 13, 22, 27).

v4: Where the anointed priest sinned, he must slaughter an animal, just like any other person.

v7: The blood was to be sprinkled before the Lord, and the rest poured out around the altar of burnt offering, also v18, 25, 30.

v8-10: The inner parts were removed, as with the Fellowship Offering, and the remainder burnt outside the camp (v12, 21); see Heb 13.12. No sweet smelling aroma here; but contrast v31, where the offering of a female goat is sacrificed on behalf of the individual.

v15: Where the community had sinned, the elders had to represent the community.

v24: Having been made aware of his sin (v23, 28), the individual comes with personal confession (also v29), and, having made the appropriate sacrifice, receives personal forgiveness (v26, 31, 35).

We note that the sin offering is for the people of Israel, not for outsiders. This continues the principle that the offerings maintain the fellowship of God's people with Him.
