have given me I lost

We're back to names again with Matt1. The Gospels take an inordinate amount of time to reconstruct the lineage of Jesus traced purely back to God. In one way, this used to trouble me. The point of His birth in a manger was to show the humble roots by which He entered the world: no place to stay except a stable, no bed except a manger, a disgraced mom, a carpenter's son, a man of Galilee, etc. All this paints a good context. And salvation is to come from the Jews, so He had to be Jewish, not arguing that point. But part of David's lineage? Direct descendant of Isaac? I'm thinking the humbleness could have been taken even further if traced from an even more unwanted lineage, no? Cain? Abraham's son by a mistress? Just thinking aloud.

I'd be remiss to ignore the 3 mentions of 14 right off the bat. As an even number, as a number containing 4, I have to say I don't see what the specialness is in 14. I also don't understand the whole lineage thing as outlined above, so I'm missing something.
