'Preached' in the Bible

but I buffet my body, and bring it into bondage: lest by any means, after that I have preached to others, I myself should be rejected.

Now I make known unto you brethren, the gospel which I preached unto you, which also ye received, wherein also ye stand,

by which also ye are saved, if ye hold fast the word which I preached unto you, except ye believed in vain.

Now if Christ is preached that he hath been raised from the dead, how say some among you that there is no resurrection of the dead?
