Genesis 47:27-31

Now [the people of] Israel lived in the country of Egypt, in [the land of] Goshen, and they gained possessions and acquired property there and were fruitful and multiplied greatly. And Jacob lived in the land of Egypt seventeen years; so the length of Jacob’s life was a hundred and forty-seven years. And when the time drew near for Israel to die, he called his son Joseph and said to him, “If now I have found favor in your sight, please put your hand under my thigh and [promise to] deal loyally and faithfully with me. Please do not bury me in Egypt, but when I lie down with my fathers [in death], you will carry me out of Egypt and bury me in their burial place [at Hebron in the cave of Machpelah].” And Joseph said, “I will do as you have directed.” Then he said, “Swear to me [that you will do it].” So he swore to him. Then Israel (Jacob) bowed in worship at the head of the bed.
