Genesis 50:1-6

Then Joseph fell upon his father’s face, and wept over him and kissed him [tenderly]. Then Joseph ordered his servants the physicians to embalm (mummify) his father. So the physicians embalmed Israel (Jacob). Now forty days were required for this, for that is the customary number of days [of preparation] required for embalming. And the Egyptians wept and grieved for him [in public mourning as they would for royalty] for seventy days. When the days of weeping and public mourning for him were past, Joseph spoke to [the nobles of] the house of Pharaoh, saying, “If now I have found favor in your sight, please speak to Pharaoh, saying, ‘My father made me swear [an oath], saying, “Hear me, I am about to die; bury me in my tomb which I prepared for myself in the land of Canaan.” So now let me go up [to Canaan], please, and bury my father; then I will return.’ ” And Pharaoh said, “Go up and bury your father, as he made you swear.”
