Jamieson, Fausset and Brown on Matthew 23:26

26. Thou blind Pharisee, cleanse first that which is within the cup and platter, that the outside of them may be clean also--In Luke (Lu 11:40) it is, "Ye fools, did not He that made that which is without make that which is within also?"--"He to whom belongs the outer life, and of right demands its subjection to Himself, is the inner man less His?" A remarkable example this of our Lord's power of drawing the most striking illustrations of great truths from the most familiar objects and incidents in life. To these words, recorded by Luke, He adds the following, involving a principle of immense value: "But rather give alms of such things as ye have, and behold, all things are clean unto you" (Lu 11:41). As the greed of these hypocrites was one of the most prominent features of their character (Lu 16:14), our Lord bids them exemplify the opposite character, and then their outside, ruled by this, would be beautiful in the eye of God, and their meals would be eaten with clean hands, though much fouled with the business of this everyday world. (See Ec 9:7).
