Genesis 50:16

16. They sent a messenger Literally, they commanded, or gave a charge to Joseph . “They charged Joseph, in their father’s name, probably by an embassy sent from Goshen to Memphis, the seat of government, although the text says nothing about messengers . Perhaps Benjamin first pleaded for them, and then they all came into his presence . Genesis 50:18. Whether Jacob actually left this message for Joseph is doubtful . If he really had such fears, he would have been likely to entreat Joseph personally, as he freely charged him concerning other things which pertained to the family welfare. It was, of course, Jacob’s wish that there should be perfect and perpetual reconciliation among his children, which often may have been expressed; but the precise form of this petition to Joseph was probably suggested by the guilty fears of the brethren, who could not fully understand the generosity and magnanimity of Joseph. They knew that Joseph would sacredly heed his father’s charge and so offered their petition in his name.” Newhall.
