Only one line of the Jews are maintained in the Bible which can be traced all the way back to Adam. This was decedents through the lineage of Seth. This is called the "royal" line because the decedents of Seth believed and followed God. Through them God's promise of the coming Messiah, the Lord Jesus Christ, would be accomplished. The Gospel of Luke, Christ's genealogy begins with Adam and Seth. (Luke 3:23-38)
