Genesis 50:3-5

New Century Version

³ It took the doctors forty days to prepare his body (the usual time it took). And the Egyptians had a time of sorrow for Jacob that lasted seventy days.

⁴ When this time of sorrow had ended, Joseph spoke to the king’s officers and said, “If you think well of me, please tell this to the king: ⁵ ‘When my father was near death, I made a promise to him that I would bury him in a cave in the land of Canaan, in a burial place that he cut out for himself. So please let me go and bury my father, and then I will return.’”
