'Three' in the Bible

Neither let us commit fornication, as some of them committed fornication, and fell in one day three and twenty thousand.

And now abide faith, hope, love; these three things; and the greater of these is love.

If any one speak with a tongue, let it be two, or at the most three, and separately, and let one interpret;

And let two or three prophets speak, and let the others judge.
