Genesis 50:4 YLT

²  and Joseph commandeth his servants, the physicians, to embalm his father, and the physicians embalm Israel;

³  and they fulfil for him forty days, for so they fulfil the days of the embalmed, and the Egyptians weep for him seventy days.

⁴  And the days of his weeping pass away, and Joseph speaketh unto the house of Pharaoh, saying, 'If, I pray you, I have found grace in your eyes, speak, I pray you, in the ears of Pharaoh, saying,

⁵  My father caused me to swear, saying, Lo, I am dying; in my burying-place which I have prepared for myself in the land of Canaan, there dost thou bury me; and now, let me go up, I pray thee, and bury my father, and return;'

⁶  and Pharaoh saith, 'Go up and bury thy father, as he caused thee to swear.'
