'Speak with Tongues' in the Bible

have all gifts of healings? do all speak with tongues? do all interpret?

and I wish you all to speak with tongues, and more that ye may prophecy, for greater is he who is prophesying than he who is speaking with tongues, except one may interpret, that the assembly may receive edification.

If, therefore, the whole assembly may come together, to the same place, and all may speak with tongues, and there may come in unlearned or unbelievers, will they not say that ye are mad?

so that, brethren, earnestly desire to prophesy, and to speak with tongues do not forbid;
