Matthew 1:25
But knew her not until she had given birth to a son. And he called his name Jesus. The chapter closes with the naming — the act that legally makes Jesus Joseph's son and therefore David's heir. The until leaves open what happened after the birth, consistent with the later references to Jesus' brothers and sisters in the gospel. The entire chapter has moved from genealogy to angelic announcement to obedient action to the naming of the child, tracing the arc from promise to fulfillment in the space of a few verses. Revelation 22:16 will end the biblical story with Jesus identifying himself as the Root and Offspring of David — the same royal identity that Matthew's first chapter establishes through genealogy, miracle, and adoption.
