Genesis 47:29-31

LXX2012(i) 29 and the days of Israel drew near for him to die: and he called his son Joseph, and said to him, If I have found favor before you, put your hand under my thigh, and you shall execute mercy and truth toward me, so as not to bury me in Egypt. 30 But I will sleep with my fathers, and you shall carry me up out of Egypt, and bury me in their sepulchre. And he said, I will do according to your word. 31 And he said, Swear to me; and he swore to him. And Israel did reverence, leaning on the top of his staff.
