John Gill Commentary Daniel 2:36

"This is the dream; and we will tell the interpretation thereof before the king." — Daniel 2:36 (ASV)

This is the dream Which Nebuchadnezzar dreamed, but had forgot, and was now punctually and exactly made known to him; for the truth of which he is appealed unto; for, no doubt, by this account, the whole of his dream, and every circumstance of it, were brought to his mind:

and we will tell the interpretation thereof before the king ; for though both the dream, and the interpretation of it, were only revealed to Daniel; yet he joins his companions with him, partly because they were now present, and chiefly because they were assisting to him in prayer for it.
