Then Daniel spoke to the king, "O king, live forever! "My God sent His angel and shut the lions' mouths, and they have not harmed me, inasmuch as I was found innocent before Him; and also toward you, O king, I have committed no crime." Daniel 6:21-22
It was the late C. I. Scofield, the author of the Scofield Study Bible who said that -
‘Within a week of my conversion I passed a picture store in St. Louis and saw, hanging in a window, a picture of Daniel looking up in the den of lions and answering the king’s questions. I was a drunken lawyer before I was converted. No one had told me about that picture, and a great hope and stood before that picture, and a great hope and faith came into my heart. I said, “Why ! These lions are all about me – my old habits and my old dins – but the God that shut the lions’ mouths for Daniel can shut them for me!’
But remember - God did not deliver Daniel from the lion's den but He did deliver him from the lion’s mouths.
