'Strange' in the Bible

One who speaks in a tongue edifies himself; but one who prophesies edifies the church [promotes growth in spiritual wisdom, devotion, holiness, and joy].

I thank God that I speak in [unknown] tongues more than all of you;

nevertheless, in public worship I would rather say five understandable words in order to instruct others, than ten thousand words in a tongue [which others cannot understand].

It is written in the Law, “By men of strange tongues and by the lips of foreigners I will speak to this people, and not even then will they listen to Me,” says the Lord.

What then is the right course, believers? When you meet together, each one has a psalm, a teaching, a revelation (disclosure of special knowledge), a tongue, or an interpretation. Let everything be constructive and edifying and done for the good of all the church.

If anyone speaks in a tongue, it should be limited to two or at the most three, and each one speaking in turn, and one must interpret [what is said].
