'Crucified' in the Bible

Is Christ divided? was Paul crucified for you? or were ye baptized in the name of Paul?

But we preach Christ crucified, unto the Jews a stumblingblock, and unto the Greeks foolishness;

For I determined not to know any thing among you, save Jesus Christ, and him crucified.

Which none of the princes of this world knew: for had they known it, they would not have crucified the Lord of glory.
