Zephaniah 3:8-9

Therefore wait for me,” declares the LORD, “for the day I will stand up to testify. I have decided to assemble the nations, to gather the kingdoms and to pour out my wrath on them— all my fierce anger. The whole world will be consumed by the fire of my jealous anger. “Then I will purify the lips of the peoples, that all of them may call on the name of the LORD and serve him shoulder to shoulder.
