John Gill Commentary Genesis 45:18

"and take your father and your households, and come unto me: and I will give you the good of the land of Egypt, and ye shall eat the fat of the land." — Genesis 45:18 (ASV)

And take your father, and your households
Or families, for they were all married persons, and had children, and no doubt servants also: all were to be brought with them,

and come unto me ;
into his kingdom, to his metropolis, and to his palace, and into his presence:

and I will give you the good of the land of Egypt ;
the best things which it affords, and the best and most fruitful part of it, as he afterwards did, which was the land of Goshen:

and you shall eat the fat of the land ;
the choicest fruits of the earth, such as were produced in fields and gardens; meaning that they should have the finest of the wheat for themselves, and the fattest pastures for their flocks.
