'Teach' in the Bible

I wrote the former account, Theophilus, about all that Jesus began to do and teach

And they called them in and ordered them not to speak or teach at all in the name of Jesus.

saying, "We gave you strict orders not to teach in this name. Look, you have filled Jerusalem with your teaching, and you intend to bring this man's blood on us!"

Now some men came down from Judea and began to teach the brothers, "Unless you are circumcised according to the custom of Moses, you cannot be saved."

They have been informed about you -- that you teach all the Jews now living among the Gentiles to abandon Moses, telling them not to circumcise their children or live according to our customs.
