if then I do not understand the power of the voice, I will be a barbarian to the one speaking, and the one speaking will be a barbarian to me.

For the one speaking with a tongue speaks not to men, but to God; for no one hears him; but he speaks mysteries in the spirit:

But I wish you all to speak with tongues, but rather that you may prophesy: but greater is the one prophesying, than the one speaking with tongues, unless he may interpret, in order that the church may receive edification.

But now, brethren, if I may come unto you speaking with tongues, what shall I profit you, unless I shall speak to you either in revelation, or knowledge, or prophecy, or in instruction?

Thus also if you through the tongue may give an indistinct word, how will that which is spoken be known? for you will be speaking into the air.
