'Well known' in the Bible

obscure and yet well-known, on the point of dying and yet I go on living, punished and yet not put to death,

I am sending with him the well-known brother whose praise for spreading the good news is ringing through all the churches.

I actually begged Titus to go, and sent the well-known brother with him. Titus did not make any money out of you, did he? Did not he and I act in the same spirit, and take the very same steps?
