Genesis 47:31 YLT

²⁹  And the days of Israel are near to die, and he calleth for his son, for Joseph, and saith to him, 'If, I pray thee, I have found grace in thine eyes, put, I pray thee, thy hand under my thigh, and thou hast done with me kindness and truth; bury me not, I pray thee, in Egypt,

³⁰  and I have lain with my fathers, and thou hast borne me out of Egypt, and buried me in their burying-place.' And he saith, 'I -- I do according to thy word;'

³¹  and he saith, 'Swear to me;' and he sweareth to him, and Israel boweth himself on the head of the bed.
