The verse centers on "daniel", "knew", "writing", "signed", "went", "house", "windows", and "open". It is saying that the verse draws attention to "daniel" and "knew", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 9's "Wherefore king Darius signed the writing and..." into verse 11's "Then these men assembled and found Daniel...", so "daniel" and "knew" belong inside that flow. In Daniel context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "daniel" and "knew" with trust shaped by these words, not by a vague optimism outside the passage.
