John 13:12-20

The Meaning of the Act: the One Exception. The disciples recognise in Him their teacher and master. They should, therefore, follow His example by helping each other even in the lowliest services. The Master had set an example which the slave need not be ashamed to copy. If they realise that by doing such things He has made it their duty to do the same, then they will be happy in the doing of them. He returns to the theme of the traitor. He knows, as they do not, the character of each disciple whom He has chosen. But it had to be. The Scripture must be fulfilled (Psalms 41:9). He has warned them, that when the event happens, instead of being discouraged, they may recognise in the fulfilment of prophecy a proof of what He is. In John 13:20 the author adds that acts of humility will not degrade them, but prove them to be His messengers, to whom all honour is due.
