Or HaChaim on Genesis 41:25/אור החיים על בראשית מ״א:כ״ה

1 את האלוקים עושה הראה לפרעה. "G'd has informed Pharaoh of what He is about to do." Berachot 55 mentions that there are three matters concerning which G'd Himself makes public annoucements; abundance of crops, famine, and a good leader. The Torah informs us that G'd had informed Pharaoh in his dream concerning all these three matters. There would be a period of abundance of agricultural products; there would come a famine; Pharaoh was given a chance to appoint a leader who could head off the impact of the famine. Even though Joseph did not mention who that person should be, the fact that G'd had withheld the interpretation of the dream from all other potential candidates for such leadership and had brought Joseph to Pharaoh's attention through the chief butler who had told him what happened to him, made Joseph a natural choice for this appointment. When the Torah says: הגיד לפרעה, this means that G'd gave Pharaoh the means to make the necessary provisions. Joseph himself spelled this out for Pharaoh in verse 33.
