Chasidut su Genesi 47:23

‎‎Genesis 47,23. “here is seed for you to sow the land; ‎and you shall give one fifth (of the harvest) to Pharaoh ‎whereas the other four fifths are for you to feed your ‎families.” A glance at Rashi’s commentary on verse ‎‎45,6 that there would be five more years of no ploughing and no ‎harvesting, poses a problem. As soon as Yaakov had arrived the ‎people had noticed an improvement in the condition of the soil, ‎so that they began using some of the seed they had, and sowed it ‎instead of using it for food as instructed. (45,5) The Egyptians ‎prepared themselves to eat the seed that they had been keeping ‎in reserve until better times would make planting more ‎propitious. Since they had violated Joseph’s instructions, he had ‎decreed that any harvest from such seed would wither and be ‎useless; this is why the Egyptians accused Joseph of decreeing to ‎let them die. This also explains why Joseph did not need to ‎appoint overseers to ensure that the Egyptians who gathered in ‎an unauthorized harvest had delivered one fifth of it to Pharaoh ‎for storage. In the third year Joseph did not decree such a curse ‎on any crop grown, stipulating that their efforts would be ‎successful only if they would deliver one fifth of their crops to ‎Pharaoh. Anyone shortchanging Pharaoh would stand to lose his ‎entire harvest.. This enables us to understand Rashi. Joseph’s ‎prediction of seven consecutive years of famine was based on the ‎people trying to grow food without Joseph’s blessing. (verse 19) ‎Even after Yaakov’s arrival, the decree of another five years of ‎famine would be cancelled only if Joseph withdrew his decree ‎against planting.
