Therefore prophesy thou against them all these words, and say unto them, The LORD shall roar from on high, and utter his voice from his holy habitation; he shall mightily roar upon his habitation; he shall give a shout, as they that tread the grapes, against all the inhabitants of the earth.
So, tell them this message: God will loudly speak from heaven and show his power. He will strongly roar over his home, like someone stomping on grapes. He will yell at everyone on Earth.
