'Speak with Tongues' in the Bible

Have all the gifts of healing? do all speak with tongues? do all interpret?

I thank my God, I speak with tongues more than ye all:

If therefore the whole church be come together into one place, and all speak with tongues, and there come in those that are unlearned, or unbelievers, will they not say that ye are mad?

Wherefore, brethren, covet to prophesy, and forbid not to speak with tongues.
