'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, did not become "yes" and "no," but has become "yes" in him.

For if the one who comes proclaims another Jesus whom we have not proclaimed, or you receive a different spirit which you did not receive, or a different gospel which you did not accept, you put up with [it] well [enough]!

Or did I commit a sin [by] humbling myself in order that you may be exalted, because I proclaimed the gospel of God to you without payment?
