The man whom Daniel saw in this vision was probably the Son of God. [1] The Jewish interpreters and some modern Christian scholars preferred the view that he was an angel. [2] The similarities between this Prayer of Manasseh , and the one Ezekiel and the Apostle John saw, argue for his being divine (cf. Ezekiel 1:26-28; Revelation 1:13-16; Revelation 2:18). However, what this man proceeded to say (esp. Daniel 10:13) has led some to prefer the view that he was an angel. [source][source][source]
Expensive linen dress is what the priests in Israel wore, and it distinguished them as God"s special servants. Likewise, the sash around this angel"s waist, evidently embroidered with or made completely of the best gold, would have identified Him as a special person. The meaning of "Uphaz" is uncertain. It may be the same as "Ophir," since the translators of the Syriac version of Jeremiah substituted "Ophir" for "Uphaz" in Jeremiah 10:9. The location of Ophir is also uncertain. It may have been in southwestern or southeastern Arabia, on the northeast African coast, or in India. [3] Alternatively, "Uphaz" may be a technical term for "refined gold." [4] The personal descriptions of this man resemble what John saw on the island of Patmos, namely: the Son of God ( Revelation 1:13-16; cf. Ezekiel 1:13-14). All these features picture a person of great glory and splendor. [source][source][source]
"The impression given to Daniel was that the entire body of the man in the vision was like a gigantic transparent jewel reflecting the glory of the rest of the vision." [5][source]
