'Teach' in the Bible

For when by reason of the time ye ought to be teachers, ye have need again that some one teach you the rudiments of the first principles of the oracles of God; and are become such as have need of milk, and not of solid food.

And they shall not teach every man his fellow-citizen, And every man his brother, saying, Know the Lord: For all shall know me, From the least to the greatest of them.
