Genesis 40:10

7 And he asked Pharaoh`s officers that were with him in ward in his master`s house, saying, Wherefore look ye so sad to-day?

8 And they said unto him, We have dreamed a dream, and there is none that can interpret it. And Joseph said unto them, Do not interpretations belong to God? tell it me, I pray you.

9 And the chief butler told his dream to Joseph, and said to him, In my dream, behold, a vine was before me;

10 and in the vine were three branches: and it was as though it budded, [and] its blossoms shot forth; [and] the clusters thereof brought forth ripe grapes:

11 and Pharaoh`s cup was in my hand; and I took the grapes, and pressed them into Pharaoh`s cup, and I gave the cup into Pharaoh`s hand.

12 And Joseph said unto him, This is the interpretation of it: the three branches are three days;

13 within yet three days shall Pharaoh lift up thy head, and restore thee unto thine office: and thou shalt give Pharaoh`s cup into his hand, after the former manner when thou wast his butler.
