“And I will show wonders in the heavens and in the earth:
Blood and fire and pillars of smoke. The sun shall be turned into darkness,
and the moon into blood, before the coming of the great and awesome day of the Lord.
And it shall come to pass that whoever calls on the name of the Lord
Shall be saved. For in Mount Zion and in Jerusalem there shall be deliverance, as the Lord has said,
among the remnant whom the Lord calls. “For behold, in those days and at that time,
when I bring back the captives of Judah and Jerusalem, I will also gather all nations,
and bring them down to the Valley of Jehoshaphat; and I will enter into judgment with them there
on account of My people, My heritage Israel,
whom they have scattered among the nations; they have also divided up My land.
Joel 2:30-3:2
