In Daniel 10:4-9, the prophet saw a vision of a man that overwhelmed him. Some expositors believe the vision was an angel, even Gabriel. John Gill maintained that it was a vision of the Son of God, that is the coming Messiah.
Dr. Gill wrote, "Not Gabriel, but the Son of God, the Messiah; who, though not as yet incarnate, yet was so in the counsel and purpose of God; had agreed in covenant to be man, was promised and prophesied of as such; and now appeared in a human form, as he frequently did before his incarnation, as a pledge of it, and showing his readiness to assume human nature."
Gill further commented about the Son of God in Daniel 10: "He appears here clothed in linen, in the habit of a priest; which office he sustains, and executes by the sacrifice of himself, and by his prevalent intercession; and may denote his purity and innocence, as well as direct us to his spotless righteousness he is the author of, which is like fine linen, clean and white."
The revelation of Christ in Daniel is confirmed in the book of Revelation 1:12-16. There we see the person of Christ described in the same way. He is described in Revelation 1:13 as "One like the Son of Man." That title for Messiah came from the book of Daniel 7:13-14. It is a term used to describe Jesus more than eighty times in the New Testament. Jesus is the Revelation.
