Genesis 41:14-16

Then Pharaoh sent and called for Joseph, and they hurriedly brought him out of the dungeon; and when Joseph shaved himself and changed his clothes [making himself presentable], he came to Pharaoh. Pharaoh said to Joseph, “I have dreamed a dream, and there is no one who can interpret it; and I have heard it said about you that you can understand a dream and interpret it.” Joseph answered Pharaoh, “It is not in me [to interpret the dream]; God [not I] will give Pharaoh a favorable answer [through me].”
