1 Corinthians 14:6:
Now, brothers, if I come to you speaking in tongues, how will I benefit you unless I bring you some revelation or knowledge or prophecy or teaching? (ESV)
But now, brothers and sisters, if I come to you speaking in tongues, how will I benefit you unless I speak to you either by way of revelation, or of knowledge, or of prophecy, or of teaching? (NASB)
Now, brethren, if I come unto you speaking with tongues, what shall I profit you, except I shall speak to you either by revelation, or by knowledge, or by prophesying, or by doctrine? (KJV)
And now, brethren, if I may come unto you speaking tongues, what shall I profit you, except I shall speak to you either in revelation, or in knowledge, or in prophesying, or in teaching? (YLT)
What is the difference between revelation, knowledge, prophecy and teaching?
