John Gill Commentary Genesis 40:9

"And the chief butler told his dream to Joseph, and said to him, In my dream, behold, a vine was before me;" — Genesis 40:9 (ASV)

And the chief butler told his dream to Joseph He listened to what Joseph said, and paid a regard to it, and began to think he might be able to interpret his dream, and therefore was forward, and the first to tell him it at once; whereas the chief baker did not seem disposed to do it, until he observed the good interpretation given of the butler's dream, (Genesis 40:16) : and said unto him, in my dream, behold, a vine [was] before me ;

it appeared to him in his dream, as if a vine sprung up at once, and stood before him; which was very suitable to his office as a butler, wine being the fruit of the vine, which he provided for the king his master, and presented to him at table.
