17 And becoming aware of it, Jesus said to them, "Why are you talking about having no bread? Do you still not perceive or understand? Are your hearts hardened? 18 Do you have eyes, and fail to see? Do you have ears, and fail to hear? And do you not remember? 19 When I broke the five loaves for the five thousand, how many baskets full of broken pieces did you collect?" They said to him, "Twelve." 20 "And the seven for the four thousand, how many baskets full of broken pieces did you collect?" And they said to him, "Seven." 21 Then he said to them, "Do you not yet understand?"

Commentary on Mark 8:11-21
(Read Mark 8:11-21)
Obstinate unbelief will have something to say, though ever so unreasonable. Christ refused to answer their demand. If they will not be convinced, they shall not. Alas! what cause we have to lament for those around us, who destroy themselves and others by their perverse and obstinate unbelief, and enmity to the gospel! When we forget the works of God, and distrust him, we should chide ourselves severely, as Christ here reproves his disciples. How is it that we so often mistake his meaning, disregard his warnings, and distrust his providence?
