Bede the Venerable
Catena Aurea · Lukasevangelium 22
And there was also a strife among them, which of them should be accounted the greatest. And he said unto them, The kings of the Gentiles exercise lordship over them; and they that exercise authority upon them are called benefactors. But ye shall not be so: but he that is greatest among you, let him be as the younger; and he that is chief, as he that doth serve. For whether is greater, he that sitteth at meat, or he that serveth? is not he that sitteth at meat? but I am among you as he that serveth.
In this rule however, given by our Lord, the great have need of no little judgment, that they do not indeed like the kings of the Gentiles delight to tyrannize over their subjects, and be puffed up with their praises, yet notwithstanding that they be provoked with a righteous zeal against the wickedness of offenders.
