'Teaching' in the Bible

The teacher must do the same in his teaching; and he who exhorts others, in his exhortation. He who gives should be liberal; he who is in authority should be energetic and alert; and he who succours the afflicted should do it cheerfully.

But as to you, brethren, I am convinced-- yes, I Paul am convinced--that, even apart from my teaching, you are already full of goodness of heart, and enriched with complete Christian knowledge, and are also competent to instruct one another.
