Mark 8:21 - Exposition

How is it that ye do not understand? A better reading here is οὔπω instead of πῶς ου) . Therefore the words should run, Do ye not yet understand ? It is as though our Lord said, "You ought to have perceived, both from my words and from my actions, that I was not speaking concerning earthly leaven or earthly bread, but concerning spiritual doctrine." St. Matthew here ( Matthew 16:12 ) is careful to tell us that this reproof of Christ quickened their intellects, and forced them to understand.
