Leviticus 4
The sin offering (chattat) addresses unintentional violations of God's commands — the inadvertent failures that the covenant's most well-intentioned members inevitably commit. Four graduated categories are established: the anointed high priest (whose sin affects the whole community, requiring a bull and blood taken into the tent of meeting itself), the whole community (same animal and ritual), the leader (a male goat with blood on the courtyard altar's horns), and the individual (a female goat or female lamb). Each category has its own blood application, its own fat-burning on the altar, and its own disposal of the offering's flesh; the most intensive rituals address the most representative violations. The chapter repeats the atonement and forgiveness formula four times — the priest makes atonement, and they will be forgiven — communicating the consistent outcome: proper sin offering, properly administered, produces real forgiveness before the Lord.
Leviticus 4:1
The Lord said to Moses. A new section of divine speech introduces the sin offering — the chattat — the offering that addresses unintentional sins and ritual impurity. The transition from the burnt, grain, and fellowship offerings to the sin offering marks a shift in the offerings' purpose: where the earlier offerings expressed devotion and communion, the sin offering addresses the problem of inadvertent violation of the covenant's requirements. The sin offering system is the covenant's provision for the inevitable failures of even well-intentioned covenant members. Romans 5:20 says where sin increased, grace increased all the more — the sin offering is the Old Testament institutional expression of that grace.
Leviticus 4:2
Say to the Israelites: when anyone sins unintentionally and does what is forbidden in any of the Lord's commands — if the anointed priest sins, bringing guilt on the people. The sin offering addresses unintentional sin — the inadvertent violation of God's commands rather than deliberate rebellion. The distinction between intentional and unintentional sin runs through the Levitical system: intentional, high-handed sin (Numbers 15:30–31) has no offering provision in the Mosaic law, communicating the seriousness of willful covenant violation. The unintentional sin that the chattat addresses is the category of sin committed through ignorance, carelessness, or human limitation — the category that includes virtually all of the covenant community's daily failures.
Leviticus 4:3
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. The anointed priest — the high priest — faces the most stringent sin offering requirement: a young bull, the most costly of the sin offering animals. The high priest's sin is not only personal but communal: bringing guilt on the people. The leader's failure affects the community he represents before God. 1 Timothy 3:2 says an overseer must be above reproach — the high priest's elevated accountability in Leviticus 4 is the foundation for the New Testament's elevated standards for those who lead God's people.
