'Teacher' in the Bible

In writing this much, brethren, with special reference to Apollos and myself, I have done so for your sakes, in order to teach you by our example what those words mean, which say, "Nothing beyond what is written!" --so that you may cease to take sides in boastful rivalry, for one teacher against another.

For this reason I have sent Timothy to you. Spiritually he is my dearly-loved and faithful child. He will remind you of my habits as a Christian teacher--the manner in which I teach everywhere in every Church.
