First Chronicles explicitly preserves the Genesis 38 family line by naming Tamar as the mother of Perez and Zerah by Judah. The genealogical notice confirms that the unusual Judah–Tamar episode becomes part of Israel’s continuing tribal history rather than an isolated family scandal.

Ruth’s Perez-to-David genealogy is preserved again within 1 Chronicles’ Judahite genealogy, including the line through Boaz, Obed, Jesse, and David, integrating Ruth’s family story into Israel’s wider tribal memory.

First Chronicles preserves the Judah-to-David ancestry through Perez, Hezron, Ram, Nahshon, Boaz, Obed, and Jesse; Matthew explicitly incorporates the same royal family line into Jesus’ genealogy. The relationship is genealogical reuse that carries Israel’s ancestral history into the Gospel’s presentation of the Messiah.
