Mark 9:33 And he came to Capernaum, and being in the house, he asked them, Of what were ye reasoning by the way?
The verse centers on "taught", "disciples", "said", "delivered", "men's", "hands", "shall", 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 30's "And going forth from thence they went..." into verse 32's "But they understood not the 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.
