Adam Clarke on Genesis 24:33

I will not eat until I have told - In Hindoostan it is not unusual for a Brahmin to enter a house and sit down, and when meat is offered, refuse to eat till he has obtained the object of his errand. Here is a servant who had his master's interest more at heart than his own. He refuses to take even necessary refreshment till he knows whether he is likely to accomplish the object of his journey. Did not our blessed Lord allude to the conduct of Abraham's servant, Joh 4:34 : My meat is to do the will of him that sent me, and to finish his work?
