How do we know Christ is from the tribe of Judah?

The New Testament clearly establishes Jesus as the descendant of Judah through genealogies presented in Matthew 1 and Luke 3. These genealogies show Jesus' rightful claim as the Messiah, fulfilling the prophecies given in the Old Testament, particularly those found in Genesis 49. The reference to the scepter not departing from Judah until Shiloh comes is understood as a direct prophecy of the coming of Christ, who brings ultimate peace and authority. This lineage assures believers of Jesus' position and fulfillment of God's promises regarding His kingdom.
