They will know that I am Yahweh their God, in that I caused them to go into captivity among the nations, and have gathered them to their own land. Then I will leave none of them captive any more.
Hebrew
וְיָדְע֗וּ כִּ֣י אֲנִ֤י יְהוָה֙ אֱלֹ֣הֵיהֶ֔ם בְּהַגְלוֹתִ֤י אֹתָם֙ אֶל־הַגּוֹיִ֔ם וְכִנַּסְתִּ֖ים עַל־אַדְמָתָ֑ם וְלֹֽא־אוֹתִ֥יר ע֛וֹד מֵהֶ֖ם שָֽׁם׃
