Joel 2:30-32 ▼

30 I will show wonders in the heavens and on the earth, blood and fire and columns [clouds] of smoke.

31 The sun will be turned to darkness and the moon to blood before the coming of the great and awesome (dreadful) Day of the LORD {Yowm YHWH}.

32 And everyone who calls on the name of the LORD {YHWH} will be saved ; for on Mount Zion and in Jerusalem (city of peace) there will be deliverance, as the LORD has promised, among the remnant called by the LORD.
