Daniel 8:16

And I heard a man's voice between the banks of Ulai, which called, and said, Gabriel, make this man to understand the vision.

And I heard a man's voice between the banks of Ulai,.... Near to which Daniel was, Daniel 8:2 and it seemed to him as if the appearance of the man was in the midst of the river, between the banks of it, from whence the voice came; or between the arms of it, it bending and winding about; or rather between Shushan and the river; or between the prophet and that: this voice was the voice of the person that appeared as a man in the preceding verse:

which called, and said, Gabriel; the voice was loud, audible, and commanding; even to an angel, one of great note, Gabriel, the man of God, the mighty one; and shows, that the person that made this appearance, and spoke in this authoritative way, was the Lord, and head of angels, even of all principalities and power, at whose beck and command they are:

make this man to understand the vision; the above vision of the ram, he goat, and little horn; give him a full explanation of it; tell him what the several figures mean, represented in it; that he may have a clear understanding of all things contained in it; the saints and people of God are sometimes instructed by angels, and particularly the prophets of old were; and which was more common in the times of the former dispensation than now; for God has not put in subjection to angels the world to come, or the Gospel dispensation, Hebrews 2:5.
