John Lightfoot on Luke 16:12

[If ye have not been faithful in that which was another man's, &c.] To apply another man's to that wealth which is given us by God, is something harsh and obscure; but to apply it to the riches of other men, makes the sense a little more easy: "If ye have been unjust in purloining the goods of other men, and will still as unjustly keep them back, what reason have you to think that others will not deal as unjustly with you, and keep back even what is yours?"
