Daniel (Greek) 6:17 (Septuagint)

¹⁵Then the king, when he heard the saying, was much grieved for Daniel, and he greatly exerted himself for Daniel to deliver him: and he exerted himself till evening to deliver him.

¹⁶Then those men said to the king, Know, O king, that the law of the Medes and Persians is, that we must not change any decree or statute which the king shall make.

— Daniel (Greek) 6:17 —

¹⁸And they brought a stone, and put it on the mouth of the den; and the king sealed it with his ring, and with the ring of his nobles; that the case might not be altered with regard to Daniel.

¹⁹And the king departed to his house, and lay down fasting, and they brought him no food; and his sleep departed from him. But God shut the mouths of the lions, and they did not molest Daniel.
