What does it mean that Jesus is the Lion of Judah?

“Judah, your brothers will praise you. Your hand will be on the neck of your enemies. Your father’s sons will bow down before you. Judah is a lion’s cub. From the prey, my son, you have gone up. He stooped down, he crouched as a lion, as a lioness. Who will rouse him up? The scepter will not depart from Judah, nor the ruler’s staff from between his feet, until he comes to whom it belongs. To him will the obedience of the peoples be.

concerning his Son, who was born of the seed of David according to the flesh,

I, Jesus, have sent my angel to testify these things to you for the assemblies. I am the root and the offspring of David; the Bright and Morning Star.”

One of the elders said to me, “Don’t weep. Behold, the Lion who is of the tribe of Judah, the Root of David, has overcome; he who opens the book and its seven seals.” I saw in the midst of the throne and of the four living creatures, and in the midst of the elders, a Lamb standing, as though it had been slain, having seven horns, and seven eyes, which are the seven Spirits of God, sent out into all the earth.

Then he came, and he took it out of the right hand of him who sat on the throne. Now when he had taken the book, the four living creatures and the twenty-four elders fell down before the Lamb, each one having a harp, and golden bowls full of incense, which are the prayers of the saints. They sang a new song, saying, “You are worthy to take the book, and to open its seals: for you were killed, and bought us for God with your blood, out of every tribe, language, people, and nation,

saying with a loud voice, “Worthy is the Lamb who has been killed to receive the power, wealth, wisdom, strength, honor, glory, and blessing!” I heard every created thing which is in heaven, on the earth, under the earth, on the sea, and everything in them, saying, “To him who sits on the throne, and to the Lamb be the blessing, the honor, the glory, and the dominion, forever and ever! Amen!” The four living creatures said, “Amen!” The elders fell down and worshiped.

Out of his mouth proceeds a sharp, double-edged sword, that with it he should strike the nations. He will rule them with an iron rod. He treads the wine press of the fierceness of the wrath of God, the Almighty. He has on his garment and on his thigh a name written, “KING OF KINGS, AND LORD OF LORDS.”

He will feed his flock like a shepherd. He will gather the lambs in his arm, and carry them in his bosom. He will gently lead those who have their young.
