Passage
But he said to them: What would you that I should do for you?
But he said to them: What would you that I should do for you?
Mark 10:34 And they shall mock him and spit on him and scourge him and kill him: and the third day he shall rise again.
Mark 10:35 And James and John, the sons of Zebedee, come to him, saying: Master, we desire that whatsoever we shall ask, thou wouldst do it for us.
Mark 10:36 But he said to them: What would you that I should do for you?
Mark 10:37 And they said: Grant to us that we may sit, one on thy right hand and the other on thy left hand, in thy glory.
Mark 10:38 And Jesus said to them: You know not what you ask. Can you drink of the chalice that I drink of or be baptized with the baptism wherewith I am baptized?
The verse centers on "said" and "should". It is saying that the verse draws attention to "said" and "should", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 35's "And James and John the sons of..." into verse 37's "And they said Grant to us that...", so "said" and "should" 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 "said" and "should" with trust shaped by these words, not by a vague optimism outside the passage.
