'Teaching' in the Bible

Keep and follow the pattern of sound teaching (doctrine) which you have heard from me, in the faith and love which are in Christ Jesus.

Study and do your best to present yourself to God approved, a workman [tested by trial] who has no reason to be ashamed, accurately handling and skillfully teaching the word of truth.

and their teaching will spread like gangrene. So it is with Hymenaeus and Philetus,

Now you have diligently followed [my example, that is] my teaching, conduct, purpose, faith, patience, love, steadfastness,

preach the word [as an official messenger]; be ready when the time is right and even when it is not [keep your sense of urgency, whether the opportunity seems favorable or unfavorable, whether convenient or inconvenient, whether welcome or unwelcome]; correct [those who err in doctrine or behavior], warn [those who sin], exhort and encourage [those who are growing toward spiritual maturity], with inexhaustible patience and [faithful] teaching.
