'Leader' in the Bible

Do not be called leaders; for One is your Leader, that is, Christ.

But it is not this way with you, but the one who is the greatest among you must become like the youngest, and the leader like the servant.

Crispus, the leader of the synagogue, believed in the Lord with all his household, and many of the Corinthians when they heard were believing and being baptized.

And they all took hold of Sosthenes, the leader of the synagogue, and began beating him in front of the judgment seat. But Gallio was not concerned about any of these things.
