In the three chapters for today Jesus explained further the kingdom of heaven in the gospel of Matthew. The two chapters of Leviticus deal with bodily discharges and the Day of Atonement.
In Matthew 20 Jesus told the parable of the workers in the vineyard, that God is always fair even when we don’t think so. Then he predicted his death. After that the mother of Zebedee’s sons asked Jesus to have her sons be the seated with Jesus in the kingdom of heaven, but Jesus answer was that is only for the Father to decide. The other disciples got angry, but Jesus admonished them all that the kingdom of heaven means to be a servant. The chapter ends with Jesus, out of compassion healed two blind men.
Leviticus 15 deals with bodily discharges.
Leviticus 16 is the apex of Leviticus and tells of all the things Aaron must do on the day of Atonement to atone for his own sins and for the sins of the people during the year that was past.
