'Instruct' in the Bible

For who has known the mind and purposes of the Lord, so as to instruct Him? But we have the mind of Christ [to be guided by His thoughts and purposes].

But in giving this next instruction, I do not praise you, because when you meet together it is not for the better but for the worse.

nevertheless, in public worship I would rather say five understandable words in order to instruct others, than ten thousand words in a tongue [which others cannot understand].
