30 And I will show wonders in the heavens and in the earth, blood, and fire, and pillars of smoke.

31 The sun shall be turned into darkness, and the moon into blood, before the great and terrible day of the LORD come.

32 And it shall come to pass, that whoever shall call on the name of the LORD shall be delivered: for in mount Zion and in Jerusalem shall be deliverance, as the LORD has said, and in the remnant whom the LORD shall call.
