17 But Jesus, being aware of it, said to them, "Why do you reason because you have no bread? Do you not yet perceive nor understand? Is your heart still hardened? 18 Having eyes, do you not see? And having ears, do you not hear? And do you not remember? 19 When I broke the five loaves for the five thousand, how many baskets full of fragments did you take up?" They said to Him, "Twelve." 20 "Also, when I broke the seven for the four thousand, how many large baskets full of fragments did you take up?" And they said, "Seven." 21 So He said to them, "How is it you do not 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?
