'Instruct' in the Bible

But as to you, brethren, I am convinced-- yes, I Paul am convinced--that, even apart from my teaching, you are already full of goodness of heart, and enriched with complete Christian knowledge, and are also competent to instruct one another.

For who has penetrated the mind of the Lord, and will instruct Him? But *we* have the mind of Christ.

but in the Church I would rather speak five words with my understanding--so as to instruct others also--than ten thousand words in an unknown tongue.

All that you have been taught by me in the hearing of many witnesses, you must hand on to trusty men who shall themselves, in turn, be competent to instruct others also.
