Daniel Chapter 6
Daniel is promoted by Darius: his enemies procure a law forbidding prayer; for the transgression of this law Daniel is cast into the lions' den: but miraculously delivered.
6:1. It seemed good to Darius, and he appointed over the kingdom a hundred and twenty governors, to be over his whole kingdom.
6:2. And three princes over them of whom Daniel was one: that the governors might give an account to them, and the king might have no trouble.
6:3. And Daniel excelled all the princes, and governors: because a greater spirit of God was in him.
6:4. And the king thought to set him over all the kingdom; whereupon the princes, and the governors, sought to find occasion against Daniel, with regard to the king: and they could find no cause, nor suspicion, because he was faithful, and no fault, nor suspicion was found in him.
6:5. Then these men said: We shall not find any occasion against this Daniel, unless perhaps concerning the law of his God.
