And men shall go into the caves of the rocks, and into the holes of the earth, from before the terror of Jehovah, and from the glory of his majesty, when he ariseth to shake mightily the earth.

to go into the caverns of the rocks, and into the clefts of the ragged rocks, from before the terror of Jehovah, and from the glory of his majesty, when he ariseth to shake mightily the earth.

He will cut down the thickets of the forest with an iron axe,And Lebanon (the Assyrian) will fall by the Mighty One.

Cry out and shout for joy, O citizens of Zion, for the Holy One of Israel acts mightily among you!"

Get yourself up on a high mountain,O Zion, bearer of good news,Lift up your voice mightily,O Jerusalem, bearer of good news;Lift it up, do not fear.Say to the cities of Judah,“Here is your God!”

Jehovah will go forth as a mighty man; he will stir up his zeal like a man of war: he will cry, yea, he will shout aloud; he will do mightily against his enemies.
