'Teach' in the Bible

But when it was now the midst of the feast Jesus went up into the temple, and began to teach.

The Jews then said to one another, “Where does this man intend to go that we will not find Him? He is not intending to go to the Dispersion among the Greeks, and teach the Greeks, is He?

Early in the morning He came again into the temple, and all the people were coming to Him; and He sat down and began to teach them.

But the Helper, the Holy Spirit, whom the Father will send in My name, He will teach you all things, and bring to your remembrance all that I said to you.
