Mark 8:16

“And they reasoned among themselves, etc..] Upon Christ's giving this caution, and recollecting with themselves, that they had forgot to buy any provisions, and take with them: saying, it is because we have no bread; that he says these words; tacitly chiding and reproving us, for our want of thought and care; (see Gill on “<401607>Matthew 16:7”).”

“See this passage explained in Matthew 16:1-12. Mark 8:12 Sighed deeply in his spirit - His heart was deeply affected at their wickedness and hypocrisy. The word “spirit” here is taken as the seat of the emotions, passions, affections. He drew groans deeply from his breast. No sign be given - That is, no such sign as they asked, to wit, a sign “from heaven.” He said a sign should be given, the same as was furnished by Jonas, Matthew 16:4. But this was not what they “asked,” nor would it be given “because” they asked it. Mark 8:15 Beware of the leaven of the Pharisees - See Matthew 16:6. Of Herod - Of the Herodians - of Herod and his followers. Matthew, instead of “Herod,” has “the Sadducees.”…”

“8:16 The disciples completely missed the point of Jesus’ warning (8:15) and forgot that because Jesus was with them, their supply of bread was irrelevant.”
