What does Isaiah 66:19 mean?

I'll put a sign among them, and I'll send some of those who survive to the nations—to Tarshish, Put, Lud (who are skilled with the bow), Tubal, Javan, and to the distant islands that haven't heard about me or seen my glory. They'll tell the nations about my greatness. Isaiah 66:19 - Modern Text Bible

(God will send messengers to far-off places so that everyone can hear about him, even those who never knew him before.)
