How do we know that Christ fulfills the Righteous Branch prophecy?

The fulfillment of the Righteous Branch prophecy in Christ is substantiated through the New Testament, which emphasizes His lineage as a descendant of David. Matthew 1:1-16 traces Jesus' genealogy back to David, demonstrating His rightful claim to the Messianic line. Moreover, the apostles distinctly recognized Jesus as the fulfillment of old testament prophecies regarding the Messiah, asserting that He came to save His people. By His life, death, and resurrection, He embodied the righteousness and faithfulness promised in Isaiah, confirming that He is the Righteous Branch who brings redemption and restoration to humanity.
