In the four chapters chosen for today, the one from the gospel of Matthew is full of promises, forgiveness and reconciliation, but also warning. The three chapters of Leviticus are more Mosaic law and regulations.
Matthew 18. To the question: “Who is the greatest in the kingdom of heaven?” Jesus called a little child. Then he expanded the question and elaborated on the subject of sin. This chapter also contains the parable of the lost sheep, which leads naturally into the subject of forgiveness, reconciliation and church discipline. Jesus also promised that “where two or three come together in my name, there am I with them”. The chapter ends with the parable of the unmerciful servant.
In Leviticus 10 two of Aaron’s sons were killed by fire for violating the command of God. But Aaron’s uncle had two sons and together with two other sons of Aaron they became the new priests and the rest of the chapter deals with how they should behave.
Leviticus 11 deals with clean (kosher) and unclean food and clean and unclean animals. (Locusts and grasshoppers are o.k.)
Finally Leviticus 12 is a short chapter and deals with purification after childbirth.
