'Speak with Tongues' in the Bible

And these signs shall accompany those having believed: in My name will they cast out demons: they will speak with tongues;

and they were all filled with the Holy Spirit, and began to speak with tongues as the Spirit gave them utterance.

For they heard them speak with tongues, and magnify God. Then answered Peter,

and Paul having laid his hands on them, the Holy Ghost came on them; and they continued to speak with tongues, and prophesy.

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

If I speak with tongues of men and of angels, but have not love, I have become sounding brass, or a clanging cymbal.

Now I would have you all speak with tongues, but rather that ye should prophesy: and greater is he that prophesieth than he that speaketh with tongues, except he interpret, that the church may receive edifying.

Even so, likewise, when ye speak with tongues, except ye speak words that have signification, how shall it be understood what is spoken? For ye shall but speak in the air.

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?

If any man speak with tongues, let it be two at once - or at the most three at once - and that by course, and let another interpret it:

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