What does Matthew 1:13 mean?

Matthew's listing of the genealogy of Jesus has followed His line from Abraham through David through the kings to the exile of Israel in Babylon. Now the line has travelled back to Israel with Zerubbabel, who became the governor of the still conquered region. The descendants of Zerubbabel through nine generations are not otherwise known in Scripture. They may have been on record and available for verification by Matthew's first-century readers, however. It's possible that Matthew skipped some generations in this section as he likely did in others. This was considered a normal and proper practice in building genealogies in his day.

Zerubbabel became the father of Abiud. Abiud fathered Eliakim. Eliakim fathered Azor.
