רמב"ן — אם בחוקותי תלכו / ונתתי גשמיכם בעתם

Q — The brachot in Bechukotai (rain, security, fertility, peace) sound like the brachot of Mishpatim ('וברך את לחמך ואת מימיך, כי אני ה' רופאך'). Are they the same thing repeated?

A — Ramban: they aren't. Those earlier brachot are individual-level — for the יחיד עובד ה' — and are 'נסים נסתרים' that look natural and could happen to a rasha too. Our parsha's brachot are national-scale — promised 'בהיות כל עמנו כלם צדיקים' — and that's why every brachah is keyed to הארץ: 'ונתנה הארץ,' 'לבטח בארצכם,' 'שלום בארץ,' 'לא תעבור בארצכם.' A whole nation continuously receiving rain at the right time, security, victory over enemies, and freedom from disease cannot be explained naturally — these nisim nistarim become publicly known precisely through their national constancy ('וראו כל עמי הארץ כי שם ה' נקרא עליך'). And — Ramban's stunning addition — when the nation is righteous, the individual within it receives more bracha than he would alone: 'לא בכללם, ולא ביחיד מהם.' The supposedly-collective reward overflows back to each.
