John Gill 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 I King Nebuchadnezzar have seen So things were represented to him by a vision in a dream: now you, O Belteshazzar, declare the interpretation thereof ;

at once, directly; as he was well assured he could, by what he had already done; having both told him his dream when forgotten by him, and the meaning of it; and therefore doubted not but he could interpret his dream, being told him: forasmuch as all the wise men of my kingdom are not able to make known unto me the interpretation ;

he had sent for them, even all of them; he had told them his dream, but they could not interpret it; see (Daniel 4:6Daniel 4:7) : but you are able, for the spirit of the holy gods is in you ;

he not only knew his ability from former experience, but for the reason here given; of which he might have more proofs than one, that the Spirit, not of impure deities, of the gods and demons of the Heathens, but of the one true, living, and holy God, who knows all things, dwelt in him; see (Daniel 4:9) .
