Daniel 6:14-18

Then, as soon as the king heard this statement, he was deeply distressed and set his mind on delivering Daniel; and even until sunset he kept exerting himself to rescue him. Then these men came by agreement to the king and said to the king, “Recognize, O king, that it is a law of the Medes and Persians that no injunction or statute which the king establishes may be changed.” Then the king gave orders, and Daniel was brought in and cast into the lions’ den. The king spoke and said to Daniel, “Your God whom you constantly serve will Himself deliver you.” A stone was brought and laid over the mouth of the den; and the king sealed it with his own signet ring and with the signet rings of his nobles, so that nothing would be changed in regard to Daniel. Then the king went off to his palace and spent the night fasting, and no entertainment was brought before him; and his sleep fled from him.
