Joel 2:31-32

Darby Translation

³¹ The sun shall be changed to darkness, and the moon to blood, before the great and terrible day of Jehovah come.

³² And it shall be that whosoever shall call upon the name of Jehovah shall be saved: for in mount Zion and in Jerusalem shall be deliverance, as Jehovah hath said, and for the residue whom Jehovah shall call.
