2 Corinthians 8:16-24

He Is Sending Three Representatives To See To The Collection and To Their Spiritual Welfare, One Of Whom Is Titus Whom They Know Well (2 Corinthians 8:16).

Three was the number of completeness from when numbers were first used, for originally men could only count up to three, which represented everything that was, apart from man and his mate, (and which is still true in some parts of the world today). Thus three representatives could be seen as the full number required.
