And he taught his disciples and said to them: The Son of man shall be betrayed into the hands of men, and they shall kill him; and after that he is killed, he shall rise again the third day.

Mark 9:31 But they understood not the word: and they were afraid to ask him.
Mark 9:32 And they came to Capharnaum. And when they were in the house, he asked them: What did you treat of in the way?
The verse centers on "taught", "disciples", "said", "shall", "betrayed", "hands", and "kill". It is saying that the verse draws attention to "taught" and "disciples", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 29's "And departing from thence they passed through..." into verse 31's "But they understood not the word and...", so "taught" and "disciples" belong inside that flow. In Mark context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "taught" and "disciples" with trust shaped by these words, not by a vague optimism outside the passage.
