Joel 2:1-3

LXX2012(i) 1 Sound the trumpet in Sion, make a proclamation in my holy mountain, and let all the inhabitants of the land be confounded: for the day of the Lord is near; 2 for a day of darkness and gloominess is near, a day of cloud and mist: a numerous and strong people shall be spread upon the mountains as the morning; there has not been from the beginning one like it, and after it there shall not be again even to the years of many generations. 3 Before them is a consuming fire, and behind them is a flame kindled: the land before them is as a paradise of delight, and behind them a desolate plain: and there shall none of them escape.
