'Proclaimed' in the Bible

For the Son of God, Jesus Christ, the one who was proclaimed among you by us -- by me and Silvanus and Timothy -- was not "Yes" and "No," but it has always been "Yes" in him.

For if someone comes and proclaims another Jesus different from the one we proclaimed, or if you receive a different spirit than the one you received, or a different gospel than the one you accepted, you put up with it well enough!

Or did I commit a sin by humbling myself so that you could be exalted, because I proclaimed the gospel of God to you free of charge?
