Jesus is called the Lion of Judah because this title symbolizes His authority, strength, and victory, fulfilling the Old Testament prophecy about the tribe of Judah. In Genesis 49:8-10, Jacob blesses his son Judah, comparing him to a lion, a symbol of power and kingship, and prophesies that the ruler's authority (the scepter) will remain with Judah's descendants. Jesus, as a descendant of Judah and King David, fulfills this prophecy as the King of Kings. The title is explicitly used in the New Testament in Revelation 5:5, where Jesus is called the Lion of the tribe of Judah, affirming His royal lineage, supreme authority, and ultimate triumph over sin and death through His role as the Messiah.
