'Teaching' in the Bible

You who give teaching to others, do you give it to yourself? you who say that a man may not take what is not his, do you take what is not yours?

But praise be to God that though you were the servants of sin, you have now given yourselves freely to that form of teaching under which you were placed;

Or the position of a Deacon of the church, let a man give himself to it; or he who has the power of teaching, let him make use of it;

Now, it is my desire, brothers, that you will take note of those who are causing division and trouble among you, quite against the teaching which was given to you: and keep away from them.
