And the seven years of dearth began to come, as Joseph had said,.... In the interpretation of Pharaoh's dreams; as soon as the seven years of plenty were over, there were quickly some appearances of the famine coming on; as particularly the river Nile not flowing to its usual height at the season of it; hence there was a drought, the earth was parched, and everything began to wither and decay, and the seed that was sown sprung not up:and the dearth was in all lands; adjoining to Egypt, as Syria, Arabia, Palestine, Canaan, &c.
but in all the land of Egypt there was bread; which was in the hands of everyone, and remained of their old stores in the years of plenty not yet exhausted, and which continued for some time after the dearth began.
It is very probable that to this seven years' drought in Egypt Ovid refers, which he makes to be nine; as does also Apollodorus . "Dicitur Aegyptus caruisse juvantibus arva Imbribus, atque annis sicca fuisse novem."
