Targum su Genesi 40:12

And Joseph said to him, This is the end of the interpretations of the dream. The three branches are the three Fathers of the world, Abraham, Izhak, and Jakob, the children of whose sons are to be enslaved in Mizraim in clay and brick (work,) and in all labour of the face of the field: but afterwards shall the be delivered by the hand of three shepherds. As thou hast said, I took the grapes and expressed them into Pharoh's cup, and gave the cup Into Pharoh's hand: It is the vial of wrath which Paroh (himself) is to drink at the last. But thou, the chief butler shalt receive a good reward concerning the good dream which thou hast dreamed; and the interpretation of it, to thyself, is this: The three branches are three days until thy liberation.

And Joseph said, This is the interpretations of the dream : The three branches are the three Fathers of the world, Abraham, Izhak, and Jakob the children of whose sons will be enslaved in the land of Mizriam and will be delivered by the band of three faithful pastors, who may be likened to the clusters. And whereas thou hast said, I took the grapes and expressed them into the cup of Pharoh and gave the cup into Pharoh's hand: It is the cup of retribution which Pharoh is to drink at the last. As to thyself, the chief of the butlers, thou wilt not lose thy reward; for this dream which thou hast dreamed is good. Nevertheless the interpretation of the dream (as relating to himself) Joseph had not told him; but afterwards he explained it, when it pleased him. And Joseph said to him, The three branches are three days.
