Genesis 50:5

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. Since his father had taken the solemn oath from him, Joseph asked the courtiers to do him the favor of applying to Pharaoh for leave of absence for him, that he might bury his father. Jacob, in anticipation of his death, probably at the time when he buried Leah, had prepared also his own burial-place in the cave of Machpelah. It is by no means a sign of a sickly morbidity if Christians purchase and prepare a cemetery lot for themselves where they hope eventually to rest, for they believe in the resurrection of the dead. Joseph's request was stated: Now, therefore, let me go up, I pray thee, and bury my father, and I will come again.
