'Teach' in the Bible

For though by this time you ought to be teachers [because of the time you have had to learn these truths], you actually need someone to teach you again the elementary principles of God’s word [from the beginning], and you have come to be continually in need of milk, not solid food.

“And it will not be [necessary] for each one to teach his fellow citizen,Or each one his brother, saying, ‘Know [by experience, have knowledge of] the Lord,’For all will know [Me by experience and have knowledge of] Me,From the least to the greatest of them.
