John 13:15

Ver. 15,16. The apostles were to take up a very high station in the gospel church, and our hearts are very prone to swell in a high opinion of ourselves, for which the nature of man taketh advantage from every thing in which we either really do excel, or can conceit that we do excel, our neighbours. Our Lord therefore, though speaking to the apostles, (some of the best of men), yet knowing they were (like Elijah) men subject to like passions with other men, addeth this to arm them against, any temptation to pride: they owned themselves as servants to Christ who was their great Lord; they had seen what he had done; he therefore applies a proverbial expression to them, which he also made use of in other cases, as Matthew 10:24 1 Thessalonians 15:20; in both which places he maketh use of it to arm them against persecutions; here, to persuade them to humility, condescension, and brotherly love.
