Passage

For he taught his disciples, and said unto them, The Son of man is delivered into the hands of men, and they shall kill him; and after that he is killed, he shall rise the third day.
Mark 9:29 And he said unto them, This kind can come forth by nothing, but by prayer and fasting.

Mark 9:31 For he taught his disciples, and said unto them, The Son of man is delivered into the hands of men, and they shall kill him; and after that he is killed, he shall rise the third day.
Mark 9:32 But they understood not that saying, and were afraid to ask him.
Mark 9:33 And he came to Capernaum: and being in the house he asked them, What was it that ye disputed among yourselves by the way?
The verse centers on "taught", "disciples", "said", "delivered", "hands", "shall", "kill", and "after". 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 30's "And they departed thence and passed through..." into verse 32's "But they understood not that saying 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.
