Daniel 6:10, 14

When Daniel knew that the document had been signed, he went to his house where he had windows in his upper chamber open toward Jerusalem. He got down on his knees three times a day and prayed and gave thanks before his God, as he had done previously.

Then the king, when he heard these words, was much distressed and set his mind to deliver Daniel. And he labored till the sun went down to rescue him.
