In those days I Daniel was mourning three full weeks.
Was mourning — Because he foresaw the many calamities that would befall the Jews for their sins, especially for destroying the Messiah, and rejecting his gospel.
 And in the four and twentieth day of the first month, as I was by the side of the great river, which is Hiddekel;
The first month — Nisan, which is March.
Hiddekel — Or Tigris.
 Then I lifted up mine eyes, and looked, and behold a certain man clothed in linen, whose loins were girded with fine gold of Uphaz:
A certain man — Very probably Christ, who appeared to Daniel in royal and priestly robes, and in so great brightness and majesty.
 Then said he unto me, Fear not, Daniel: for from the first day that thou didst set thine heart to understand, and to chasten thyself before thy God, thy words were heard, and I am come for thy words.
He — Not Christ, but Gabriel.
 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.
Withstood me — God suffered the wicked counsels of Cambyses to take place awhile; but Daniel by his prayers, and the angel by his power, overcame him at last: and this very thing laid a foundation of the ruin of the Persian monarchies.
Michael — Michael here is commonly supposed to mean Christ.
I remained — To counter-work their designs against the people of God.
 And when he had spoken such words unto me, I set my face toward the ground, and I became dumb.
I set my face — I prostrated myself upon the earth.
And I became dumb — Thro' astonishment.
 And, behold, one like the similitude of the sons of men touched my lips: then I opened my mouth, and spake, and said unto him that stood before me, O my lord, by the vision my sorrows are turned upon me, and I have retained no strength.
One like the sons of men — This likewise seems to have been Gabriel.
I have retained no strength — Tho' he appeared to him, and spake to him as a man, yet Daniel could not bear his presence, without some dread.
 Then said he, Knowest thou wherefore I come unto thee? and now will I return to fight with the prince of Persia: and when I am gone forth, lo, the prince of Grecia shall come.
To fight — To oppose his mischievous designs.
 But I will shew thee that which is noted in the scripture of truth: and there is none that holdeth with me in these things, but Michael your prince.
Michael — Christ alone is the protector of his church, when all the princes of the earth desert or oppose it.
