'Apostles' in the Bible

For, I think, God has exhibited us apostles last of all, as men condemned to death; because we have become a spectacle to the world, both to angels and to men.

Do we not have a right to take along a believing wife, even as the rest of the apostles and the brothers of the Lord and Cephas?

And God has appointed in the church, first apostles, second prophets, third teachers, then miracles, then gifts of healings, helps, administrations, various kinds of tongues.

All are not apostles, are they? All are not prophets, are they? All are not teachers, are they? All are not workers of miracles, are they?

then He appeared to James, then to all the apostles;

For I am the least of the apostles, and not fit to be called an apostle, because I persecuted the church of God.
