'Instruct' in the Bible

For who has known the mind of the Lord, who shall instruct him? But we have the mind of Christ.

but in the assembly I desire to speak five words with my understanding, that I may instruct others also, rather than ten thousand words in a tongue.

And the things thou hast heard of me in the presence of many witnesses, these entrust to faithful men, such as shall be competent to instruct others also.
