You blind Pharisee, cleanse first that which is within the cup and platter, that the outside of them may be clean also.
All Commentaries on Matthew 23:26 Go To Matthew 23
John Chrysostom
AD 407
But neither when He says, These ought ye to have done, and not to leave the others undone, does He say it as introducing a legal observance; away with the thought; neither with regard to the platter and the cup, when He said, Cleanse that which is within the cup and platter, that the outside of them may be clean also, does He bring us unto the old regard for little things, but on the contrary indeed, He does all things to show it to be superfluous. For He said not, Cleanse the outside of them also, but that which is within, and the outside is sure to follow.
And besides, neither is it concerning a cup and platter he is speaking, but of soul and body, by the outside meaning the body, by the inside the soul. But if with regard to the platter there be need of that which is within much more with regard to you.
But ye do the contrary, says He, observing things trifling and external, you neglect what are great and inward: whence very great mischief arises, for that thinking you have duly performed all, you despise the other things; and despising them, you do not so much as strive or attempt to perform them.
