'Den of Lions' in the Bible

All the presidents of the kingdom, the governors, and the princes, the counsellers, and the captains, have consulted together to establish a royal statute, and to make a firm decree, that whosoever shall ask a petition of any God or man for thirty days, save of thee, O king, he shall be cast into the den of lions.

Then they came near, and spake before the king concerning the king's decree; Hast thou not signed a decree, that every man that shall ask a petition of any God or man within thirty days, save of thee, O king, shall be cast into the den of lions? The king answered and said, The thing is true, according to the law of the Medes and Persians, which altereth not.

Then the king commanded, and they brought Daniel, and cast him into the den of lions. Now the king spake and said unto Daniel, Thy God whom thou servest continually, he will deliver thee.

Then the king arose very early in the morning, and went in haste unto the den of lions.

And the king commanded, and they brought those men which had accused Daniel, and they cast them into the den of lions, them, their children, and their wives; and the lions had the mastery of them, and brake all their bones in pieces or ever they came at the bottom of the den.
