'Preach' in the Bible

For Christ did not send me to baptize, but to preach the gospel -- and not with clever speech, so that the cross of Christ would not become useless.

but we preach about a crucified Christ, a stumbling block to Jews and foolishness to Gentiles.

For if I preach the gospel, I have no reason for boasting, because I am compelled to do this. Woe to me if I do not preach the gospel!

What then is my reward? That when I preach the gospel I may offer the gospel free of charge, and so not make full use of my rights in the gospel.

Whether then it was I or they, this is the way we preach and this is the way you believed.
