Jesus’ genealogy in the Book of Matthew
Matthew traced Jesus’ lineage back before he even mentions Jesus’ birth. The book of Matthew is a link between the Old and New Testament and Matthew’s goal was to convince his readers that Jesus was the long awaited Messiah. Genealogies were very important to the Jews and Matthew traces Jesus’ line through David and Abraham, a common criterion for being the Messiah.
When Titus destroyed the Temple in AD70 all the Jewish genealogies were destroyed. So only Jesus’ genealogical tables in Matthew and Luke remain to give the lineal descent from David.
Therefore no other living man could legally prove he’s of that line and the rightful heir to the throne! It’s almost like God saying, “OK, the Messiah came. We have no further use for genealogies.”
The only family line God recognizes now is whether we are related to Him through His Son!
