Genesis 50:2

Joseph fell on his father’s face, wept on him, and kissed him.

Forty days were used for him, for that is how many days it takes to embalm. The Egyptians wept for Israel for seventy days.

When the days of weeping for him were past, Joseph spoke to Pharaoh’s staff, saying, “If now I have found favor in your eyes, please speak in the ears of Pharaoh, saying,

‘My father made me swear, saying, “Behold, I am dying. Bury me in my grave which I have dug for myself in the land of Canaan.” Now therefore, please let me go up and bury my father, and I will come again.’”
