But they vnderstoode not the word that he spake to them.

The verse centers on "vnderstoode", "word", and "spake". It is saying that the verse draws attention to "vnderstoode" and "word", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 49's "Then said he vnto them Howe is..." into verse 51's "Then hee went downe with them and...", so "vnderstoode" and "word" belong inside that flow. In Luke context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "vnderstoode" and "word" with trust shaped by these words, not by a vague optimism outside the passage.
