'Three' in the Bible

Again, let us not give way to the desires of the flesh, as some of them did, of whom twenty-three thousand came to their end in one day.

But now we still have faith, hope, love, these three; and the greatest of these is love.

If any man makes use of a tongue, let it not be more than two, or at the most three, and in turn; and let someone give the sense:

And let the prophets give their words, but not more than two or three, and let the others be judges of what they say.
