Daniel 10

Daniel 10:13

We cannot possibly doubt that this prince of the kingdom of the Persians was a hostile power that befriended the nation of the Persians as an enemy of God's people. For in order to hinder the good which he saw would result from the archangel's solution to the question for which the prophet prayed to the Lord, in his jealousy he strove to prevent the saving comfort of the angel from reaching Daniel too speedily and strengthening the people of God, over which the archangel Gabriel was set. — CONFERENCE 8:13
