Genesis 42:3 - Ellicott's Commentary On The Whole Bible

Joseph’s ten brethren. — Either their cattle and households had been already greatly reduced by the mortality caused by the famine, or each patriarch must have taken a number of servants with him, if the corn carried home was to be enough to be of any real use. We learn, however, that they still possessed flocks and herds when they went down into Egypt (Genesis 47:1), and also households of servants (Genesis 46:5, where see Note). Joseph, moreover, besides the wagons and their contents, sends twenty loads of provisions for the use of his father by the way (Genesis 45:21-23), showing thereby that there were very many mouths to feed. Probably, therefore, there was some small amount of rain in Palestine, though not enough for the support of crops of corn. There would be, however, supplies of milk and flesh, but not much more.
