Threescore and Ten Days — Genesis 50:1–6

And Joseph fell upon his father's face, and wept upon him, and kissed him.

And Joseph commanded his servants the physicians to embalm his father: and the physicians embalmed Israel. And forty days were fulfilled for him; for so are fulfilled the days of embalming: and the Egyptians wept for him threescore and ten days.

And when the days of weeping for him were past, Joseph spake unto the house of Pharaoh, saying,

If now I have found favor in your eyes, speak, I pray you, in the ears of Pharaoh, saying, My father made me swear, saying, Lo, I die: in my grave which I have digged for me in the land of Canaan, there shalt thou bury me. Now therefore let me go up, I pray thee, and bury my father, and I will come again.

And Pharaoh said,

Go up, and bury thy father, according as he made thee swear.
