Joel 2:29 KJV

And ye shall know that I am in the midst of Israel, and that I am the LORD your God, and none else: and my people shall never be ashamed.

And it shall come to pass afterward, that I will pour out my spirit upon all flesh; and your sons and your daughters shall prophesy, your old men shall dream dreams, your young men shall see visions:

And I will shew 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 great and the terrible day of the LORD come.
