Genesis 41:8-13
8 And it came to pass in the morning that his spirit was troubled; and he sent and called for all the magicians of Egypt, and all the wise men thereof: and Pharaoh told them his dream; but there was none that could interpret them unto Pharaoh.
9 Then spake the chief butler unto Pharaoh, saying, I do remember my faults this day:
10 Pharaoh was wroth with his servants, and put me in ward in the captain of the guard's house, both me and the chief baker:
11 And we dreamed a dream in one night, I and he; we dreamed each man according to the interpretation of his dream.
12 And there was there with us a young man, an Hebrew, servant to the captain of the guard; and we told him, and he interpreted to us our dreams; to each man according to his dream he did interpret.
13 And it came to pass, as he interpreted to us, so it was; me he restored unto mine office, and him he hanged.
In the morning his spirit was troubled. A sting was left in Pharaoh’s heart, that he might know that he had to deal with God; for this anxiety was as an inward seal of the Spirit of God, to give authenticity to the dream; although Pharaoh deserved to be deprived of the advantage of this revelation, when he resorted to magicians and soothsayers, who were wont to turn the truth of God into a lie. He was convinced by a secret impulse that the dream sent by God portended something important; but he seeks out impostors, who would darken, by their fallacies, the light which was divinely kindled; and it is the folly of the human mind to gather to itself leaders and teachers of error. No doubt he believed them to be true prophets; but because he coluntarily closes his eyes, and hastens into the snare, his false opinion forms no sufficient excuse for him; otherwise men, by merely shutting their eys, might have some plausible pretext for mocking God with impunity: and we see that many seek protection for themselves in that gross ignorance in which they knowingly and purposely involve themselves. Pharaoh, therefore, as far as he was able, deprived himself of the benefit of the prophecy, by seeking for magicians as the interpreters of it. So we see it daily happens that many lose hold of the truth, because they either bring a cloud over themselves by their own indolence, or too eagerly catch at false and spurious inventions. But because the Lord would, at that time, succour the kingdom of Egypt, he drew Pharaoh back, as by main force, from his error.
There was none that could interpret. By this remedy God provided that the dream should not fail. We know what an inflated and impudent race of men these soothsayers were, and how extravagantly they boasted. How did it then happen that they gave the king no answer, seeing they might have trifled in any way whatever with a credulous man, who willingly suffered himself to be deluded? Therefore, that he might desist from inquiry, he is not allowed to find what he had expected in his magicians: and the Lord so strikes dumb the wicked workers of deceit, that they cannot even find a specious explanation of the dreams. Moreover, by this method, the anxiety of the king is sharpened; because he considers that what has escaped the sagacity of the magicians must be something very serious and secret. By which example we are taught, that the Lord provides the best for us, when he removes the incitements of error from those of us who wish to be deceived; and we must regard it as a singular favour, when either false prophets are silenced, or their fatuity is, in any manner, discovered to us. As for the rest, the king might hence easily gather how frivolous and nugatory was the profession of wisdom, in which the Egyptians gloried above all others; for they boasted that they were possessed of the science of divination which ascended above the very heavens. But now, as far as they are concerned, the king is without counsel, and, being disappointed of his hope, is filled with anguish; nevertheless he does not so awake as to shake off his superstition. Thus we see that men, though admonished, remain still in their torpor, Whence we plainly perceive how inexcusable is the obstinacy of the world, which does not desist from following those delusions which are openly condemned as foolishness, from heaven.
Then spake the chief butler. Although the Lord took pity on Egypt, yet he did it not for the sake of the king, or of the country, but that Joseph might, at length, be brought out of prison; and further, that, in the time of famine, food might be supplied to the Church: for although the produce was stored with no design beyond that of providing for the kingdom of Egypt; yet God chiefly cared for his Church, which he esteemed more highly than ten worlds. Therefore the butler, who had resolved to be silent respecting Joseph, is constrained to speak for the liberation of the holy man. In saying, I do remember my faults this day, he is understood by some as confessing the fault of ingratitude, because he had not kept the promise he had given. But the meaning is different; for he could not speak concerning his imprisonment, without interposing a preface of this kind, through fear, lest suspicion should enter into the mind of the king, that his servant thought himself injured; or, should take offence, as if the butler had not been sensible of the benefit conferred upon him. We know how sensitive are the minds of kings; and the courtier had found this out by long experience: therefore he begins by acknowledging that he had been justly cast into prison. Whence it follows that he was indebted to the clemency of the king for restoration to his former state.
