Jacob was gone. Joseph and his brothers mourned his death. Joseph ordered that his father be embalmed as Egyptians were embalmed before burial. We know from archaeology that ancient Egyptians, at least the wealthy, were mummified for burial. So Joseph was following the customs of his time when he had Jacob embalmed. The Bible tells us that it took 40 days for the embalming to be completed. We are also told that the Egyptians mourned him for 70 days. This tells me that the Israelites were respected because of Joseph. They were not slaves at the beginning of their time in Egypt.
