'Known' in the Bible

This is the revelation of Jesus the Messiah, which God gave him to show his servants the things that must happen soon. He made it known by sending his messenger to his servant John,

"I know what you've been doing. You are known for being alive, but you are dead. Be alert, and strengthen the things that are left, which are about to die. I note that your actions are incomplete before my God.

He captured the dragon, that ancient serpent, also known as the Devil and Satan, and tied him up for a thousand years.
