How do we know Jesus is from the line of David?

The significance of Jesus being from the lineage of David is rooted in the royal covenant established in 2 Samuel 7, where God promised that David's lineage would produce a king whose reign would be eternal. In the New Testament, both Matthew and Luke present genealogies that trace Jesus' lineage back to David, affirming this prophetic fulfillment. Romans 1:3 explicitly states that Jesus Christ is of the seed of David according to the flesh, further solidifying His connection to this pivotal covenant. This fulfillment is not just historical; it underscores the theological importance of Jesus as the Messiah who brings God's promises of salvation and establishes the eternal kingdom foretold by the prophets.
