The Gospel of Matthew begins with the genealogy of Jesus. One important reason he begins this way is because it is theologically important to him to begin by referring to Jesus as the son of David and the son of Abraham. Jesus is, for Matthew, the Messiah who has descended from David, as foretold by the scriptures. Another reason why Matthew begins with the genealogy of Jesus is to show that God continues to act in human history, and that he acts now, in a decisive way, in the sending of his Son. God is not simply a God in the heavens, but a God who is Emmanuel, God with us.
Matthew’s genealogy consists of three parts. The first, which begins with Abraham, ends with the Davidic kingship. The second begins with David and ends with the deportation or exile to Babylon. The third begins with the exile and ends with the birth of the Messiah, Jesus Christ.
Matthew calls attention to the number fourteen at the end of the genealogy and, though a variety of suggestions have been offered as to why he chose fourteen, the simplest explanation is that the numerical value of “David” in Hebrew (DWD) is fourteen (d, 4; w, 6; d, 4). By this symbolism, Matthew points out that the promised "son of David" (1:1), the Messiah, has come. And, if the third set of fourteen is short one member (to solve this problem some count Jechoniah twice), perhaps it suggests that, just as God cuts short the time of distress for the sake of his elect, so also he mercifully shortens the period from the Exile to Jesus, the Messiah.
Unlike Luke’s genealogy, which does not name a single woman, Matthew’s genealogy mentions four women besides Mary. These are Tamar, Ruth, Rahab, and Uriah’s wife, Bathsheba. Several reasons have been offered as to why Matthew mentioned these four women. Three of these reasons are widely accepted today: (a) there was something extraordinary about their union with their partners; (b) they showed initiative or played an important role in God’s plan and so came to be considered as instruments of God’s providence or of his Holy Spirit; and (c) all four women (except Mary) were Gentiles and Matthew wants to show that in God’s plan of salvation, the Gentiles were included from the beginning.
Through this, Matthew probably wants to show that God wants all to be saved and that he uses the unexpected to triumph over human obstacles and that he intervenes on behalf of his planned Messiah. This combination of scandalous and irregular union, and divine intervention, explains Matthew’s choice of the four women.
What are the points that Matthew makes in his genealogy and what does he want to achieve by it? Matthew clearly wants to show that Jesus is the fulfillment of all Israel’s hopes. The story of Jesus is part of the story of God’s constant saving acts throughout the history of Israel. God involves himself in the nitty-gritty of life. Despite the constant infidelity of Israel, God remained faithful and, in a definitive way, directed its history towards its fulfillment in Jesus Christ.
Matthew is also interested in affirming that the plan of God has often been fulfilled in history in unanticipated and “irregular” ways, as was the case in the birth of Jesus from Mary, and that Matthew is interested in showing that God worked through irregular, even scandalous ways, and through women who took initiative, like Tamar and Ruth. Yet the main reason for Matthew’s inclusion of these women corresponds to one of the Gospel’s primary themes: the inclusion of the Gentiles in the plan of God from the beginning. All of the men in Jesus’ genealogy are necessarily Jewish. But the four women mentioned, with the exception of Mary, are Gentiles, “outsiders,” or considered to be such in Jewish tradition. Just as the following story shows Jesus to be the fulfillment of both Jewish and Gentile hopes, so also the genealogy shows that the Messiah comes from a Jewish line that already includes Gentiles.
By showing Jesus as descended from David, Matthew wants to explicate that Jesus is the royal heir to the throne. Jesus, however, thorough his life, cross, death and resurrection will redefine the meaning of Kingship as never before.
Finally, Matthew wants to stress that God is active constantly in history and involved in the lives of his people. He works not only miraculously but also ordinarily in human effort, pain, and struggle to bring people to the kingdom.
