Joel 2:31-32

Young's Literal Translation

³¹ The sun is turned to darkness, and the moon to blood, Before the coming of the day of Jehovah, The great and the fearful.

³² And it hath come to pass, Every one who calleth in the name of Jehovah is delivered, For in mount Zion and in Jerusalem there is an escape, As Jehovah hath said, And among the remnants whom Jehovah is calling!
