'Den' in the Bible

All the presidents of the kingdom, the prefects, and the satraps, the counsellors, and the governors 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, except of thee, O king, he shall be cast into the den of lions.

Then they came near, and spoke before the king concerning the king's decree: Hast thou not signed a decree, that every man that shall ask anything of any god or man within thirty days, except 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 may not be revoked.

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

And a stone was brought, and laid upon the mouth of the den; and the king sealed it with his own signet, and with the signet of his nobles, that the purpose might not be changed concerning Daniel.

Then the king arose with the light at break of day, and went in haste unto the den of lions.

And when he came near unto the den, he cried with a mournful voice unto Daniel: the king spoke and said unto Daniel, O Daniel, servant of the living God, hath thy God whom thou servest continually been able to save thee from the lions?

Thereupon was the king exceeding glad, and commanded that they should take Daniel up out of the den. So Daniel was taken up out of the den, and no manner of hurt was found upon him, because he believed in his God.

And the king commanded, and they brought those men who had accused Daniel, and cast them into the den of lions, them, their children, and their wives; and the lions had the mastery of them, and broke all their bones in pieces ere they came to the bottom of the den.
