Flavius Josephus, Antiquities of the Jews
William Whiston, A.M., Ed.

[64] He therefore said, that in his sleep he saw three clusters of grapes hanging upon three branches of a vine, large already, and ripe for gathering; and that he squeezed them into a cup which the king held in his hand; and when he had strained the wine, he gave it to the king to drink, and that he received it from him with a pleasant countenance. This, he said, was what he saw; and he desired Joseph, that if he had any portion of understanding in such matters, he would tell him what this vision foretold. Who bid him be of good cheer, and expect to be loosed from his bonds in three days' time, because the king desired his service, and was about to restore him to it again; for he let him know that God bestows the fruit of the vine upon men for good; which wine is poured out to him, and is the pledge of fidelity and mutual confidence among men; and puts an end to their quarrels, takes away passion and grief out of the minds of them that use it, and makes them cheerful. "Thou sayest that thou didst squeeze this wine from three clusters of grapes with thine hands, and that the king received it: know, therefore, that this vision is for thy good, and foretells a release from thy present distress within the same number of days as the branches had whence thou gatheredst thy grapes in thy sleep. However, remember what prosperity I have foretold thee when thou hast found it true by experience; and when thou art in authority, do not overlook us in this prison, wherein thou wilt leave us when thou art gone to the place we have foretold; for we are not in prison for any crime; but for the sake of our virtue and sobriety are we condemned to suffer the penalty of malefactors, and because we are not willing to injure him that has thus distressed us, though it were for our own pleasure." The cupbearer, therefore, as was natural to do, rejoiced to hear such an interpretation of his dream, and waited the completion of what had been thus shown him beforehand.
