Yoel 3:15-16

The shemesh and the yarei'ach shall be darkened, and the kokhavim shall withdraw their shining. HASHEM also shall roar out of Tziyon, and utter His voice from Yerushalayim; and the heavens and the earth shall shake; but HASHEM will be the machseh (refuge) of His people, and the maoz of the Bnei Yisroel.
