1 Corinthians 14:36-39

What? came the word of God out from you? or came it unto you only? If any man think himself to be a prophet, or spiritual, let him acknowledge that the things that I write unto you are the commandments of the Lord. But if any man be ignorant, let him be ignorant. Wherefore, brethren, covet to prophesy, and forbid not to speak with tongues.
