קבלה על ישעיהו 66:12

"...that Pharaoh dreamed, and behold, he stood by the river" concerns the dream of Joseph, because every river is part of Joseph the Righteous. This is the hidden meaning of the thought that whoever sees a river in his dream sees peace, as it is written, "I will extend peace to her like a river" (Isaiah 66:12), so "river" alludes to Joseph.
