John Gill Commentary Daniel 4:24

"this is the interpretation, O king, and it is the decree of the Most High, which is come upon my lord the king:" — Daniel 4:24 (ASV)

This is the interpretation, O king Of this part of the dream, namely, what follows in the two next verses:

and this is the decree of the most High ; called before the decree of the watchers, (Daniel 4:17) , and is no other than the decree of that sovereign and absolute Being, whose purposes are unfrustrable:

which is come upon my lord the king ; the decree had passed concerning him, and would be most certainly fulfilled: and, because of the certainty of it, it is represented as if it was; for it would shortly and surely come upon him, exactly as it was determined, and by the dream signified.
