(32) They understood not that saying.--The words, giving once more a kind of psychological analysis of the disciples' thoughts, are not in St. Matthew, but are found in St. Luke. They imply the continuance of the perplexity described in Mark 9:10.

Verse 32. - But they understood not the saying, and were afraid (ἐφοβοῦντο) to ask him; St. Matthew (Matthew 17:23) says, "They were exceeding sorry." They saw that something very dreadful was about to happen. Their Master's words and looks showed them this. But it was a mystery to them. All his words staggered them, but especially those which spoke of his rising again. They did not understand whether it was an entrance into a higher state or a restoration to a common life. They did not understand why he was to die, and how these words of his about his death could agree with those in which he had told them that his kingdom was at hand. Perhaps, on the whole, they inclined to the view most pleasing to them, that Christ would not die; for this was what they wished and most desired. And so they tried to persuade themselves that his words respecting his sufferings and death had some other hidden meaning; and were to be understood in a figurative sense and not a literal. But anyhow, they dreaded to ask him.

9:30-40 The time of Christ's suffering drew nigh. Had he been delivered into the hands of devils, and they had done this, it had not been so strange; but that men should thus shamefully treat the Son of man, who came to redeem and save them, is wonderful. Still observe that when Christ spake of his death, he always spake of his resurrection, which took the reproach of it from himself, and should have taken the grief of it from his disciples. Many remain ignorant because they are ashamed to inquire. Alas! that while the Saviour teaches so plainly the things which belong to his love and grace, men are so blinded that they understand not his sayings. We shall be called to account about our discourses, and to account for our disputes, especially about being greater than others. Those who are most humble and self-denying, most resemble Christ, and shall be most tenderly owned by him. This Jesus taught them by a sign; whoever shall receive one like this child, receives me. Many have been like the disciples, ready to silence men who have success in preaching to sinners repentance in Christ's name, because they follow not with them. Our Lord blamed the apostles, reminding them that he who wrought miracles in his name would not be likely to hurt his cause. If sinners are brought to repent, to believe in the Saviour, and to live sober, righteous, and godly lives, we then see that the Lord works by the preacher.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.
