Daniel 6:26
I make a decree, That in every dominion of my kingdom men tremble and fear before the God of Daniel: for he is the living God, and stedfast for ever, and his kingdom that which shall not be destroyed, and his dominion shall be even unto the end.
The decree belongs to the reign of Darius the Mede, also called Darius the Median, after he took the throne formerly held by the Babylonian rulers following the fall of Babylon, in his two-year reign over Medo-Persia. He at once reorganized the government by setting 120 princes over the kingdom and three presidents over them, of whom Daniel was first, so that the princes might give account to them and the king should suffer no loss. Daniel was preferred above the presidents and princes because an excellent spirit was in him, and the king intended to set him over the whole realm. In that honored service Daniel's conduct was blameless and faithful, with neither error nor fault found in him. Jealous leaders sought occasion for complaint against him but could find none, and his enemies could find no grounds to accuse him except in connection with the law of his God.
He remained steadfast in worship, kneeling in prayer with hands raised toward an open window. After he came out unharmed from the lions' den, his deliverance illustrated that faith in God remains steady in danger and gloom just as in prosperity. That faith reaches beyond what is seen and holds to eternal realities. Moved by the deliverance, Darius wrote to all peoples, nations, and languages in all the earth and throughout his kingdom. In every dominion he decreed that men tremble and fear before the God of Daniel.
He confessed Him as the living God and steadfast forever, whose kingdom shall not be destroyed and whose dominion shall endure even to the end. As the result of Daniel's faithfulness, faithful service, deliverance, and association with the rulers, a heathen ruler and the peoples of his empire were brought to acknowledge God's power and enduring kingdom. Thus the living God was publicly feared and His indestructible kingdom was honored in every dominion beneath the sun. This is an example of how rulers who witnessed God's servants under persecution were led to make His greatness and supremacy known to their people. The decree itself shows God preparing the hearts of kings to show favor to His repentant exiled people while they were seeking the Lord in prayer and studying the prophecies foretelling their deliverance.
