Joel 2:31-32

American Standard Version

³¹ The sun shall be turned into darkness, and the moon into blood, before the great and terrible day of Jehovah cometh. ³² And it shall come to pass, that whosoever shall call on the name of Jehovah shall be delivered; for in mount Zion and in Jerusalem there shall be those that escape, as Jehovah hath said, and ^[a]among the remnant those whom Jehovah doth call.
