'Well known' in the Bible

And Isaiah is even bold enough to say, "I was found by those who did not seek me; I became well known to those who did not ask for me."

Greet Andronicus and Junia, my compatriots and my fellow prisoners, who are well known to the apostles, who were also in Christ before me.

your christianity is very well known in the world. I am glad therefore on your behalf: but yet I would have you as expert in that which is good, as unpractis'd in what is evil.
