‏ Genesis 47:18-21

Verse 18

When that year was ended - The sixth year of the famine, they came unto him the second year, which was the last or seventh year of the famine, in which it was necessary to sow the land that there might be a crop the succeeding year; for Joseph, on whose prediction they relied, had foretold that the famine should continue only seven years, and consequently they expected the eighth year to be a fruitful year provided the land was sowed, without which, though the inundation of the land by the Nile might amount to the sixteen requisite cubits, there could be no crop.
Verse 19

Buy us and our land for bread - In times of famine in Hindostan, thousands of children have been sold to prevent their perishing. In the Burman empire the sale of whole families to discharge debts is very common - Ward's Customs.
Verse 21

And as for the people, he removed them to cities - It is very likely that Joseph was influenced by no political motive in removing the people to the cities, but merely by a motive of humanity and prudence. As the corn was laid up in the cities he found it more convenient to bring them to the place where they might be conveniently fed; each being within the reach of an easy distribution. Thus then the country which could afford no sustenance was abandoned for the time being, that the people might be fed in those places where the provision was deposited.
