'Three' in the Bible

And now there remain: faith [abiding trust in God and His promises], hope [confident expectation of eternal salvation], love [unselfish love for others growing out of God’s love for me], these three [the choicest graces]; but the greatest of these is love.

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].

Let two or three prophets speak [as inspired by the Holy Spirit], while the rest pay attention and weigh carefully what is said.
