The lion hath roared! Who will not fear? The Lord GOD hath spoken! Who can but prophesy?

And he said: "The LORD will roar from Zion, and utter His voice from Jerusalem; and the habitations of the shepherds shall mourn, and the top of Carmel shall wither."

The young lions roar after their prey and seek their meat from God.

"They shall walk after the LORD; He shall roar like a lion. When He shall roar, then the children shall tremble from the west.
