Joel 2:31-32

King James Version

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 whosoever shall call on the name of the Lord shall be delivered: for in mount Zion and in Jerusalem shall be deliverance, as the Lord hath said, and in the remnant whom the Lord shall call.
