The Crooked Line of Descent

Matthew’s gospel is the first book of the NT and the very beginning of Matthew (1:1-17) is one of those boring genealogies that we’re used to seeing in Genesis. Just as the use of genealogies in Genesis served the purpose of linking Abraham to Noah and to Adam, Matthew uses a genealogy to link Jesus to Abraham. In v. 17 Matthew explicitly divides his list into three parts:

1. From Abraham to David
2. From David to the Babylonian Exile
3. From the Babylonian Exile to Jesus

The words Matthew uses (“book of the genesis”) to introduce his genealogy in v. 1 hearken back to the toledot formula we saw at the beginning of each of the genealogies in Genesis. He also specifies that Jesus Christ (= messiah) is both son of David and son of Abraham. By tracing Jesus’ descent through the Davidic line of kings, Matthew emphasizes the sonship of David, an important theme in the first chapter of his infancy narrative. By tracing descent back to Abraham, Matthew is also stressing his second theme that Jesus is the realization of God’s promise to Abraham by whom “all nations of the earth shall bless themselves” (Gen 22:18). This promise will be fulfilled when the magi come to pay homage to the Christ child.

Artificial Tree

Matthew’s construction is highly artificial. Luke (3:23-38) also provides a genealogy of Jesus. Unlike Matthew who works forward from Abraham, Luke works backwards from Jesus all the way to “Adam, son of God.” A quick comparison of the two genealogies show them diverging after David, with Matthew tracing Jesus’ descent through Solomon and Luke through a non-regal son, Nathan. This poses a problem for biblical inerrantists. A popular explanation is that Matthew cites Jesus’ genealogy through Joseph while Luke documents Mary’s genealogy. It is true that Matthew is focused on Joseph while Luke focuses on Mary, but Luke writes “Joseph, the son of Heli” and Matthew says “Jacob the father of Joseph.” They are both clearly describing Joseph's line of descent.

Matthew says that there were fourteen generations in each of his three parts, but that’s only true of the second section. In both the first and last parts there are fourteen names, but only thirteen generations. Oops! And to get fourteen generations in the second part, he had to skip over several kings. According to the OT Joram was not the father of Uzziah; there were three additional generations between these two kings. More problems for inerrantists.

Jesus' family tree. The genealogy of Jesus according to Matthew lists an assortment of known and unknown names and links Jesus to Abraham and the rest of the OT.

From Abraham to David

The first section has some familiar names, beginning with the patriarchs of Genesis: Abraham, Isaac, Jacob, and Judah. Anyone familiar with the OT stories would know of the covenant made with Abraham and his act of faith in being willing to sacrifice Isaac. But the patriarchs also behaved badly at times. Jacob cheated his elder brother out of his birthright and Judah and his brothers sold Joseph into slavery. Perhaps Matthew wants to remind the reader of that by specifically mentioning “Judah and his brothers.” Matthew also said that Judah was the father of Perez and Zerah by Tamar. It’s very odd in a genealogy to mention the mother. We’ll return to this later.

From David to the Babylonian Exile

Starting at the high point in Israel’s history with David and Solomon, we pass through a series of kings that ends with the destruction of Jerusalem by the Babylonians and the end of the monarchy. David gets mentioned more than anyone else in the OT. Yet he sinned by taking Bathsheba, the wife of Uriah the Hittite, and then arranging for Uriah’s death when Bathsheba became pregnant. Matthew alludes to that incident in citing David as “the father of Solomon by the wife of Uriah.” With the exception of Hezekiah and Josiah, all the other kings in the list were corrupt, incompetent or idolators. Although they were God’s representatives on earth, the kings listed in the second section were hardly exemplars of faith.

From the Babylonian Exile to Jesus

The final section covers the period from the exile in Babylon to the return and occupation by first the Greeks and then the Romans. It lists mostly unknown names. We don’t know where Matthew got these names and they don’t match the few post-exilic names that are documented in 1 Chronicles 3:19-24. Just as the line of Jesus’ descent goes through rich and powerful kings, it also wends its way through poor and powerless unknowns. If the names and stories we know in the other section are any judge, then the final section has its mix of saints and sinners – mostly sinners – as well.

What about the Women?

Scattered through Matthew’s genealogy are a few names of the mothers who made their contribution to the line of descent. From Genesis, we know of Sarah, Rebekah, and Rachel, but those are not names Matthew cites. Instead, he gives us Tamar, Rahab, Ruth, and “the wife of Uriah” (Bathsheba). Why mention these women and not the others?

The one thing these women seem to have in common is that there was something irregular or scandalous about them. For example, Tamar’s husbands died before she had a child. As father-in-law, it was Judah’s duty to give her children. When he shirked his duty, Tamar took matters into her own hands and disguised herself as a prostitute. Rahab actually was a prostitute who aided the spies sent into Jericho. Ruth was a Moabite who literally threw herself at the feet of Boaz to get him to marry her. Bathsheba’s story has already been mentioned. Matthew is using these case studies in scandalous relationships to prepare us for the similarly irregular nature of the birth of Jesus.

The Big Picture

The big picture Matthew is drawing indicates that God has a plan, but that plan does not proceed apace without some twists and turns. God has to work with fallible human beings. We are not simply subject to fate, but retain our free will. Similarly, God is free to choose whom he will. It is not always the oldest son or the favored son who appears in the line of succession. Sometimes, the actions of women carry great import in moving the plan forward. 

The genealogy is Matthew’s way of saying that God writes straight with crooked lines, acting through a collection of saints and sinners, the powerful and the powerless to bring about the fulfillment of his promise to Abraham in Jesus Christ.
