Genealogies are dull, right?
Well, perhaps to us, and if so, then Matthew 1 is mostly quite dull too. Whatever may be said about inspiration, the gospel of Matthew displays some solid literary skill, though, so it seems like a rather odd oversight to put such a boring passage right at the beginning, whilst trying to capture the audience's attention. I would like to give some back-story to this opening to show why this genealogy is probably the most interesting in the whole New Testament, and perhaps the whole Bible. So to do that, some history:
Long before the first century AD, Israel had been formed from the patriarchs, and to Abraham had been given the first covenant promises - a nation through him, and the promised land (corresponding to modern day Palestine). The Israelites had managed to conquer the promised land, and lived there for quite a few generations. In this period another covenant was made, one with king David, that there would always be a king from the line of David. The Son of David would reign Israel forever, the prophecy said. This dynasty lasted for an enormously long time - but not forever. Disaster came.
The nation of Israel was exiled, and no king was on the throne. A few centuries later, Israel returns, but her king is not Davidic. The Maccabees took back Judea from the Seleucids, setting up the Hasmonean dynasty...but they were not the real deal. They were not from the line of David. Their kingdom could not last if God's prophecy was to be fulfilled, if God's Messiah would reign - for he had to be of the line of David.
As exciting as the return from exile was, there was no true king on the throne. Herod is enthroned by Rome, but when he concocts his genealogy attempting to show Davidic descent, nobody believes him. This causes him a great deal of paranoia, as we shall see in the next bit of the infancy narrative of Matthew, however now it suffices to say that still, the king was not on the throne.
Were was the king? Who was to be God's anointed one, the Christ? Had God forgotten his promises to Abraham and David?
This is the atmosphere into which Matthew writes his opening genealogy:
"This is the record of the genealogy of Jesus Christ, the son of David, the son of Abraham." (Matthew 1:1, NET)
Picture yourself in the first century, despaired by God's seeming absence. You hear someone excitedly opening up a scroll, there is some news to be heard! And this news opens up saying "here is the lineage of Jesus Christ, the son of David, the son of Abraham." Not just any of the descendents of David, of which there are many. Here is Jesus, the Christ, the true son of David. The King has come.
