Charles Ellicott Commentary Daniel 4:18

"This dream I, king Nebuchadnezzar, have seen; and thou, O Belteshazzar, declare the interpretation, forasmuch as all the wise men of my kingdom are not able to make known unto me the interpretation; but thou art able; for the spirit of the holy gods is in thee." — Daniel 4:18 (ASV)

This dream. —More correctly translated, This in a dream I saw — i.e., it was communicated to me in a vision.
