Leviticus - Chapter 4
In this chapter we read about the fourth offering - the Sin Offering.
This is a required atonement for unintentional sins, for the confession of sins, for the forgiveness of sins and for the cleansing from defilement. Part of the offering is burnt within the Tabernacle. But the rest is taken outside the camp.
The link to Jesus is explained for us in the letter to the Hebrews - chapter 13:
"Under the old system, the high priest brought the blood of animals into the Holy Place as a sacrifice for sin, and the bodies of the animals were burned outside the camp. So also Jesus suffered and died outside the city gates to make his people holy by means of his own blood. So let us go out to him, outside the camp, and bear the disgrace he bore. For this world is not our permanent home; we are looking forward to a home yet to come. Therefore, let us offer through Jesus a continual sacrifice of praise to God, proclaiming our allegiance to his name."
