Therefore, behold, I will make them know, this once I will make them know my power and my might, and they shall know that my name is YHWH.
Jeremiah 16:21

When God says he will make the nations to know his name, take it as a threat. In the first Exodus, he taught the nations through the ten plagues in Egypt. In the Greater Exodus, he will teach them through the plagues of the Great Tribulation.
