1 Chronicles - Chapter 3

In this chapter we see the descendants of King David, with the royal line set out both as kings in Judah and as the royal line after the exile.

The list follows David's son, Solomon, and through him the kings of Israel and the royal line after the exile.  This list is used in Matthew to show that Jesus has a claim to the royal throne through his inheritance through his legal father Joseph - although he is not a blood descendant through this line.

This chapter also mentions David's other sons, including Nathan.  The genealogy in Luke follows the descendants of Nathan and shows that Jesus is a blood descendant of David through his mother Mary.  This is why the two genealogies split after they get to David.
