Zephaniah 3:8-9

8Therefore wait ye upon me, saith Yhwh, until the day that I rise up to the prey: for my determination is to gather the nations, that I may assemble the kingdoms, to pour upon them mine indignation, even all my fierce anger: for all the earth shall be devoured with the fire of my jealousy. 9For then will I turn to the people a pure language, that they may all call upon the name of Yhwh, to serve him with one consent.12
