Book of Matthew discusses the lineage, birth, and early life of Christ in the first two chapters. From there, the book discusses the ministry of Jesus. The descriptions of Christ's teachings are arranged around "discourses" such as the Sermon on the Mount in chapters 5 through 7. Chapter 10 involves the mission and purpose of the disciples; chapter 13 is a collection of parables; chapter 18 discusses the church; chapter 23 begins a discourse about hypocrisy and the future. Chapters 21 through 27 discuss the arrest, torture, and execution of Jesus. The final chapter describes the Resurrection and the Great Commission.
Matthew's purpose is to present Jesus Christ as the King and Messiah of Israel, he quotes from the Old Testament more than any of the other three gospel writers.
