13 The prince of the kingdom of Persia withstood me twenty-one days, but Michael, one of the chief princes, came to help me, for I was left there with the kings of Persia, 14 and came to make you understand what is to happen to your people in the latter days. For the vision is for days yet to come." 15 When he had spoken to me according to these words, I turned my face toward the ground and was mute. 16 And behold, one in the likeness of the children of man touched my lips. Then I opened my mouth and spoke. I said to him who stood before me, "O my lord, by reason of the vision pains have come upon me, and I retain no strength. 17 How can my lord's servant talk with my lord? For now no strength remains in me, and no breath is left in me." 18 Again one having the appearance of a man touched me and strengthened me. 19 And he said, "O man greatly loved, fear not, peace be with you; be strong and of good courage." And as he spoke to me, I was strengthened and said, "Let my lord speak, for you have strengthened me." 20 Then he said, "Do you know why I have come to you? But now I will return to fight against the prince of Persia; and when I go out, behold, the prince of Greece will come. 21 But I will tell you what is inscribed in the book of truth: there is none who contends by my side against these except Michael, your prince.

Commentary on Daniel 10:10-21
(Read Daniel 10:10-21)
Whenever we enter into communion with God, it becomes us to have a due sense of the infinite distance between us and the holy God. How shall we, that are dust and ashes, speak to the Lord of glory? Nothing is more likely, nothing more effectual to revive the drooping spirits of the saints, than to be assured of God's love to them. From the very first day we begin to look toward God in a way of duty, he is ready to meet us in the way of mercy. Thus ready is God to hear prayer. When the angel had told the prophet of the things to come, he was to return, and oppose the decrees of the Persian kings against the Jews. The angels are employed as God's ministering servants, Hebrews 1:14. Though much was done against the Jews by the kings of Persia, God permitting it, much more mischief would have been done if God had not prevented it. He would now more fully show what were God's purposes, of which the prophecies form an outline; and we are concerned to study what is written in these Scriptures of truth, for they belong to our everlasting peace. While Satan and his angels, and evil counsellors, excite princes to mischief against the church, we may rejoice that Christ our Prince, and all his mighty angels, act against our enemies; but we ought not to expect many to favour us in this evil world. Yet the whole counsel of God shall be established; and let each one pray, Lord Jesus, be our righteousness now, and thou wilt be our everlasting confidence, through life, in death, at the day of judgment, and for evermore.
