Yo’ĕl (Joel) 2:1-2

Blow a shophar in Tsiyon, and sound an alarm in My set-apart mountain! Let all the inhabitants of the earth tremble, for the day of יהוה is coming, for it is near: a day of darkness and gloom, a day of clouds and thick darkness, like the morning clouds spread over the mountains – a people many and strong, the like of whom has never been, nor shall there ever be again after them, to the years of many generations.
