'Others' in the Bible

If I be not an apostle unto others, yet doubtless I am to you: for the seal of mine apostleship are ye in the Lord.

If others be partakers of this power over you, are not we rather? Nevertheless we have not used this power; but suffer all things, lest we should hinder the gospel of Christ.

But I keep under my body, and bring it into subjection: lest that by any means, when I have preached to others, I myself should be a castaway.

Yet in the church I had rather speak five words with my understanding, that by my voice I might teach others also, than ten thousand words in an unknown tongue.
