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:
Then I lifted up mine eyes - from the ground, on which they had been fixed in his mourning.
And behold a certain man - literally, one man. An angel of the highest order; because in Daniel 8:16 he commands Gabriel to make Daniel to understand the vision; and in Daniel 12:6 one of the two angels inquires of him how long it would be until the end predicted.
Clothed in linen - the raiment of priests, being the symbol of sanctity, as more pure than wool (Exodus 28:42); also of prophets (Jeremiah 13:1); and of angels (Revelation 15:6).
Whose loins were girded with fine gold of Uphaz - i:e., with a girdle interwoven with gold (Revelation 1:13).
