'Den' in the Bible

All the presidents of the kingdom, the deputies and the satraps, the counselors and the governors, have consulted together to establish a royal statute, and to make a strong decree, that whoever shall ask a petition of any god or man for thirty days, except of you, 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: Haven't you signed an decree, that every man who shall make petition to any god or man within thirty days, except to you, O king, shall be cast into the den of lions? The king answered, The thing is true, according to the law of the Medes and Persians, which doesn't alter.

Then the king commanded, and they brought Daniel, and cast him into the den of lions. [Now] the king spoke and said to Daniel, Your God whom you serve continually, he will deliver you.

A stone was brought, and laid on the mouth of the den; and the king sealed it with his own signet, and with the signet of his lords; that nothing might be changed concerning Daniel.

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

When he came near to the den to Daniel, he cried with a lamentable voice; the king spoke and said to Daniel, Daniel, servant of the living God, is your God, whom you serve continually, able to deliver you from the lions?

Then 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 kind of harm was found on him, because he had trusted in his God.

The king commanded, and they brought those men who 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 broke all their bones in pieces, before they came to the bottom of the den.
