Daniel 10:13

Dan 10:13 But the prince of the kingdom of Persia withstood me one and twenty days: but, lo, Michael, one of the chief princes, came to help me; and I remained there with the kings of Persia.

Ver. 13. But the prince of the kingdom of Persia withstood me. ] By this prince of Persia some understand wicked Cambyses. Others, a an evil angel, that by his suggestions swayed Cambyses to oppose and retard the rebuilding of the temple. There is a principal devil, prince of this world; and there are, as some hold, princes or principal spirits in countries and nations under him. Eph 6:12

But, lo, Michael, one of the chief princes, ] i.e., Christ the Lord of angels, head of the Church. Daniel 12:1-13 : 1Ki 12:7 By these chief princes may be understood the three persons in trinity, or the created angels. The Septuagint translate the word ευσθυμουντων , the cheerful ones, who serve the Lord readily, freely, and joyfully in his wars; making Zion as dreadful to all her enemies, Psa 68:17 as those angels once made Sinai, at the delivery of the law.

And I remained there with the kings of Persia. ] With Cambyses and his counsellors, to repress their rage, and to blast their designs against the Church; which, when it is opposed, the holy angels interpose. Psa 34:7
