‘And their fame was heard in Pharaoh's house saying, “Joseph's brothers have come.” And Pharaoh was well pleased, and his servants. And Pharaoh said to Joseph, “Say to your brothers, ‘Do this. Load up your beasts and go, get yourselves into the land of Canaan, and take your father and your households and come to me, and I will give you the good of the land of Egypt and you will eat the fat of the land. Now that you are commanded, do this. Take for yourselves wagons from the land of Egypt for your little ones and for your wives, and bring your father and come. Also do not bother with your stuff. For the good of all the land of Egypt is yours.'
The news about Joseph's brothers follows quickly, and reaches Pharaoh's house a little while after the news that he has been heard weeping with some ‘foreigners' (Genesis 45:2). And it is a tribute to Joseph that Pharaoh is himself pleased at the news, and his high officials also.
Then Pharaoh takes a hand with all the munificence of a Pharaoh. Joseph had intended to bring his family over quietly but now it comes into the public domain. The brothers are to load their asses with a superabundance of provisions, and they are to take wagons to fetch all the members of the family tribe (their households). (Pharaoh could not conceive of travelling without wagons). Then they are all to come to Egypt where they will be given the very best. Indeed, they do not need to bring any extraneous stuff with them for Pharaoh will provide them with all they need and more.
“Wagons”. These were probably large, two-wheeled, covered ox-carts (compare Numbers 7:3).
