A three-level quotation is introduced with the words "Joseph spoke ... saying." The second level begins with the words "If now I have found favor in your eyes, please speak to Pharaoh, saying."
Here "house of Pharaoh" stands for the officials that make up Pharaoh's royal court. Alternate translation: "Joseph spoke to Pharaoh's officials" (See: [[rc://en/ta/man/translate/figs-metonymy]])
The phrase "find favor" is an idiom which means to be approved of by someone. Also, the eyes represent seeing, and seeing represents thoughts or judgment. Alternate translation: "If I have found favor with you" or "If you are pleased with me" (See: [[rc://en/ta/man/translate/figs-idiom]] and [[rc://en/ta/man/translate/figs-metaphor]])
