Mark 9:32
But they understood not that saying, and were afraid to ask him.
But they understood not that saying,.... Meaning either the whole of what he had said, concerning his delivery, death, and resurrection: and which then must be interpreted with some limitation; for they must understand the sense of his words, which were clear and express; especially concerning his death, which affected their minds with trouble and grief; for Matthew says, "they were exceeding sorry upon it", See Gill on "Matthew 17:23"; but they could not understand how it could be, and upon what account, and for what end, so holy and good, and innocent a man as he was, could be put to death; nor how this could consist with his character, as the Son of God, the Messiah, and king of Israel; and with the notions they had of the Messiah's abiding for ever, and setting up a temporal kingdom on earth: or this may regard only his resurrection from the dead; which whether it was to be taken in a literal or mystical sense, they could not tell:
and were afraid to ask him; lest they should be upbraided with their ignorance and stupidity, as they had been lately rebuked by him for their unbelief, and the neglect of their duty; and as Peter had been severely reprimanded for expostulating with him about the selfsame things, delivered by him to them, not before.
