8 Thus also Joseph bound his brethren by an oath, and said to them:— When God shall remember you, take up my bones from hence with you. And according to the word of Joseph his brethren did, and kept the oath a hundred and twenty-five years. At that time when the hosts of the Lord went out from the land of Egypt, then Moses took up the bones of Joseph when he went forth. And the bones of the righteous man were more precious and better in his estimation than the gold and the silver that the children of Israel took from Egypt when they spoiled them.
And the bones of Joseph were forty years in the wilderness; and at that time when Moses fell asleep, he gave them in inheritance to Joshua the son of Nun. The bones of Joseph his father were better in his estimation than all the spoil of that land which he subdued. And why did Moses give the bones of Joseph to Joshua? Clearly, because he was of the tribe of Ephraim the son of Joseph. And he buried them in the land of promise, that there might be in that land a treasure, (even) that of the bones of Joseph (that were) buried therein.
And also at the time that Jacob was dying, he blessed his tribes, and showed them what would happen to them in the latter days, and said to Reuben:— Reuben, you are my firstborn, might and the beginning of my strength. You have gone astray; as water, you shall not abide, because you went up to your father's bed. Truly you defile my couch and went up. From the time that Jacob fell asleep until the time that Moses fell asleep two hundred and thirty-three years elapsed.
Then Moses wished by his priestly power to absolve Reuben from his transgression and sin, in that he had lain with Bilhah, his father's concubine; that when his brethren should rise, he might not be cut off from their number. So he said in the beginning of his blessing:— Reuben shall live and not die, and shall be in the number.
