Rashi on Leviticus 26:5/רש"י על ויקרא כ״ו:ה׳

1והשיג לכם דיש את בציר AND YOUR THRESHING SHALL REACH UNTO THE VINTAGE — This means that there will be plenty of threshing-work so that you will be busy with it till the vintage, and with the vintage you will be busy till the time of sowing (Sifra, Bechukotai, Chapter 1 7).

2ואכלתם לחמכם לשבע AND YE SHALL EAT YOUR BREAD TO THE FULL — This means, one will eat only a little and it will become blessed in his bowels (will fully satisfy him) (Sifra, Bechukotai, Chapter 1 7; cf. Rashi on Leviticus 25:19).
