Apocalipse 5:5

And one of the elders... — Better, And one from among the elders saith unto me, Weep not; behold, the Lion, which is of the tribe of Judah, the Boot of David, conquered (so as) to open the roll, and the seven seals thereof. The position of the word “conquered” is emphatic, and should receive greater prominence. The verse has been translated, “Behold, one conquered, (even) the Lion...” The right to open the roll is thus made to turn, as we noticed before, not merely on the divine Sonship of our Lord, but upon His victory: He conquered, and so opens the secret purposes of God to His Church. The thought is exactly parallel with other scriptures which give emphasis to the work of redemption. It is “for the suffering of death” that Christ is clothed “with glory and honour” (Hebreus 2:9). Similarly St. Paul traces the exaltation of Christ as the outcome of His humiliation, “wherefore (i.e., in consequence of His humiliation) God also hath highly exalted Him” (Filipenses 2:9). Thus Christ, who in conquest is seen to be the power of God, in revealing the true philosophy of history is seen to be the wisdom of God.

The Lion of the tribe of Juda — The lion was the ancient symbol of the tribe of Judah. Jacob described his son as “a lion’s whelp” (Gênesis 49:9); the standard of Judah in the Israelitish encampment is said to have been a lion. It was the symbol of strength, courage, and sovereignty.

The Root of David. — The Lion is also the representative of the royal house of David. “Christ cometh of the seed of David” (comp. Marcos 12:35 with João 8:42); the prophets have described Him as the Branch, which would spring from the ancient stock (Isaías 11:1; Zacarias 6:12). But there seems also a reference to the deeper thought that He who is the Branch is also the Root (comp. Isaías 11:10); He is the one who was David’s Lord (Mateus 22:41), and “the true source and ground of all power” to David and David’s tribe, and of all who looked to Him, and not to themselves, for strength.
