John Gill Commentary Genesis 41:7

"And the thin ears swallowed up the seven rank and full ears. And Pharaoh awoke, and, behold, it was a dream." — Genesis 41:7 (ASV)

And the seven thin ears devoured the seven rank and full ears ,
&c.] So it appeared to Pharaoh in his dream, which must be very amazing to behold, and unaccountable how it should be: and Pharaoh awoke, and, behold, [it was] a dream ;
not a real fact, but a dream; yet not a common dream, but had some important signification in it; it not vanishing from his mind, but abode upon it, which made him conclude there was something more than common in it, and made him very desirous to have the interpretation of it.
