Genesis 26:12

An hundredfold. Although the patriarchs lived, generally speaking, a semi-nomadic life, their habits differed considerably from those of present-day Bedouins. The latter neither till the land nor own great herds and flocks as the patriarchs did. Although the Gerar valley is exceptionally fertile, a hundredfold increase in the yield of grain is about the maximum for Palestine, where it is normally thirtyfold to fiftyfold (see Matthew 13:23). The special blessing of God rested upon Isaac.
