New Revised Standard Version, Anglicised

³ they spent forty days in doing this, for that is the time required for embalming. And the Egyptians wept for him for seventy days.

⁴ When the days of weeping for him were past, Joseph addressed the household of Pharaoh, ‘If now I have found favour with you, please speak to Pharaoh as follows: ⁵ My father made me swear an oath; he said, “I am about to die. In the tomb that I hewed out for myself in the land of Canaan, there you shall bury me.” Now therefore let me go up, so that I may bury my father; then I will return.’
