'Known' in the Bible

This is the revelation of Jesus Christ [His unveiling of the divine mysteries], which God [the Father] gave to Him to show to His bond-servants (believers) the things which must soon take place [in their entirety]; and He sent and communicated it by His angel (divine messenger) to His bond-servant John,

But to the rest of you in Thyatira, who do not hold this teaching, who have not explored and known the depths of Satan, as they call them—I place no other burden on you,

“Who will not fear [reverently] and glorify Your name, O Lord [giving You honor and praise in worship]?For You alone are holy;For all the nations shall come and worship before You,For Your righteous acts [Your just decrees and judgments] have been revealed and displayed.”

Then he said to me, “These words are faithful and true.” And the Lord, the God of the spirits of the prophets, has sent His angel [as a representative] to show His bond-servants the things that must soon take place.
