Now when Daniel knew that the written document was signed, he entered his house (now in his roof chamber he had windows open toward Jerusalem); and he continued kneeling on his knees three times a day, praying and giving thanks before his God, as he had been doing previously.
Daniel 6:8 Now, O king, establish the injunction and sign the written document so that it may not be changed, according to the law of the Medes and Persians, which may not be revoked.”
Daniel 6:9 Therefore King Darius signed the written document, that is, the injunction.
Daniel 6:10 Now when Daniel knew that the written document was signed, he entered his house (now in his roof chamber he had windows open toward Jerusalem); and he continued kneeling on his knees three times a day, praying and giving thanks before his God, as he had been doing previously.
Daniel 6:11 Then these men came by agreement and found Daniel seeking to make a petition and making supplication before his God.
Daniel 6:12 Then they came near and said before the king concerning the king’s injunction, “Did you not sign an injunction that any man who seeks to make a petition to any god or man besides you, O king, for thirty days, is to be cast into the lions’ den?” The king answered and said, “The word is certain, according to the law of the Medes and Persians, which may not be revoked.”
The verse centers on "daniel", "knew", "written", "document", "signed", "entered", "house", and "roof". 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 "Therefore King Darius signed the written document..." into verse 11's "Then these men came by agreement and...", 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.
