In the reading for today Jesus via Matthew told of the final offering; himself, and in three chapters of Leviticus are a telling of the offering system performed in the Old Testament.
In Matthew 16 the Jews demanded a sign. Jesus ttold them the there will be no sign other than the sign of Jonah: Three days and three nights in the belly of a great fish. The disciples had forgotten to bring bread and Jesus coincidentally told them : Beware if the yeast of the Pharisees and the Sadducees. Huh? Jesus had to explain to them he meant the doctrine, not the literal yeast. Then Peter made his famous confession: “Thou art the Christ, the Son of the living God.” Right after that Jesus predicted his death, unto which Peter said “Never” and Jesus answered “Get behind me, Satan.” Strong words. And then Jesus said “Whosoever will lose his life for my sake shall find it.” Finally Jesus predicted his transfiguration.
Leviticus 4 defines the sin offering.
Leviticus 5 completes the sin offering and continues with the guilt offering.
And Leviticus 6 tells of the restitution necessary in the burnt offering, the grain offering and the sin offering.
