Isaiah 5:29; Isaiah 31:4

29 Their roaring shall be like a lion, they shall roar like young lions: yea, they shall roar, and lay hold of the prey, and shall carry it away safe, and none shall deliver it.

4 For thus hath the LORD spoken unto me, Like as the lion and the young lion roaring on his prey, when a multitude of shepherds is called forth against him, he will not be afraid of their voice, nor abase himself for the noise of them: so shall the LORD of hosts come down to fight for mount Zion, and for the hill thereof.
