Joel 2:31-32

World English Bible

³¹ The sun will be turned into darkness,
    and the moon into blood,
    before the great and terrible day of Yahweh comes.
³² It will happen that whoever will call on Yahweh’s name shall be saved;
    for in Mount Zion and in Jerusalem there will be those who escape,
    as Yahweh has said,
    and among the remnant, those whom Yahweh calls.
