1 Corinthians 14:26-27King James Version (KJV)
26 How is it then, brethren? when ye come together, every one of you hath a psalm, hath a doctrine, hath a tongue, hath a revelation, hath an interpretation. Let all things be done unto edifying.
27 If any man speak in an unknown tongue, let it be by two, or at the most by three, and that by course; and let one interpret.
