Expositor's Bible Commentary Commentary Mark 8:18

"Having eyes, see ye not? and having ears, hear ye not? and do ye not remember?" — Mark 8:18 (ASV)

They should not have been so concerned over the bread. They should have remembered how abundantly Jesus had provided for them on two occasions —so much so that on both occasions they had leftover bread to collect. He, the Provider, was with them in the boat. What else could they want or need?
