“For three weeks Gabriel wrestled with the powers of darkness, seeking to counteract the influences at work on the mind of Cyrus. … All that heaven could do in behalf of the people of God was done. The victory was finally gained; the forces of the enemy were held in check all the days of Cyrus, and all the days of his son Cambyses”. — Ellen G. White, Prophets and Kings, p. 572.
“What great honor is shown to Daniel by the Majesty of heaven! He comforts His trembling servant and assures him that his prayer has been heard in heaven. In answer to that fervent petition the angel Gabriel was sent to affect the heart of the Persian king. The monarch had resisted the impressions of the Spirit of God during the three weeks while Daniel was fasting and praying, but heaven’s Prince, the Archangel, Michael, was sent to turn the heart of the stubborn king to take some decided action to answer the prayer of Daniel”. — Ellen G. White, The Sanctified Life, p. 51.
