Yeshayah 27:12-13

Orthodox Jewish Bible

¹² And it shall come to pass in Yom Hahu, that Hashem shall thresh from the flowing Nahar (i.e., [Euphrates] River) unto the Wadi Mitzrayim, and ye shall be gathered one by one, O ye Bnei Yisroel.

¹³ And it shall come to pass in Yom Hahu, that the shofar gadol shall be blown, and they shall come which were ready to perish in Eretz Ashur (Assyria), and those of the Golus of Eretz Mitzrayim, and shall worship Hashem in the Har HaKodesh in Yerushalayim.
