Genesis 50:3-10

Forty days were required for him, for such are the days required for those who are embalmed; and the Egyptians mourned for him seventy days. Now when the days of his mourning were past, Joseph spoke to the household of Pharaoh, saying, “If now I have found favor in your eyes, please speak in the hearing of Pharaoh, saying, ‘My father made me swear, saying, “Behold, I am dying; in my grave which I dug for myself in the land of Canaan, there you shall bury me.” Now therefore, please let me go up and bury my father, and I will come back.’ ” And Pharaoh said, “Go up and bury your father, as he made you swear.” So Joseph went up to bury his father; and with him went up all the servants of Pharaoh, the elders of his house, and all the elders of the land of Egypt, as well as all the house of Joseph, his brothers, and his father’s house. Only their little ones, their flocks, and their herds they left in the land of Goshen. And there went up with him both chariots and horsemen, and it was a very great gathering. Then they came to the threshing floor of Atad, which is beyond the Jordan, and they mourned there with a great and very solemn lamentation. He observed seven days of mourning for his father.
