John Gill Commentary Genesis 45:21

"And the sons of Israel did so: and Joseph gave them wagons, according to the commandment of Pharaoh, and gave them provision for the way." — Genesis 45:21 (ASV)

And the children of Israel did so As Pharaoh commanded, and Joseph from him directed them to do:

and Joseph gave them wagons, according to the commandment of Pharaoh: and beasts, either horses or oxen to draw them, and these not empty, though the principal use of them was to fetch his father and his family, and their goods:

and gave them provision for the way: both going and returning, as much as would suffice for both.
