'Preach' in the Bible

But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed.

As we said before, so say I now again, If any man preach any other gospel unto you than that ye have received, let him be accursed.

To reveal his Son in me, that I might preach him among the heathen; immediately I conferred not with flesh and blood:

And I went up by revelation, and communicated unto them that gospel which I preach among the Gentiles, but privately to them which were of reputation, lest by any means I should run, or had run, in vain.

And I, brethren, if I yet preach circumcision, why do I yet suffer persecution? then is the offence of the cross ceased.
