Tafsiran Ulangan 28:2: Chizkuni, Ibn Ezra, Kli Yakar & Sforno

ובאו עליך כל הברכות האלה, “and all these blessings will come upon you;” you will not have to strive to secure them.

they will come i.e., they will come of themselves.

“And all these blessings shall come upon you and overtake you.” Regarding being supreme over all the nations of the earth, it says and the Lord will set you, attributing this matter to the Holy One, blessed be He. But regarding the acquisition of other blessings, it says they will come on their own. This implies [a question]: who will pursue them, that it says and overtake you? The explanation is that whoever pursues authority, it flees from him; but whoever flees from authority, authority pursues him (Tanchuma Vayikra 3). And authority is the source of all blessings, for what a servant acquires, his master acquires. Therefore it says, and the Lord will set you supreme, etc. because this is the authority which is not fitting for you to seek or strive after, and nevertheless the Lord will give it to you. From then on, authority will pursue you and overtake you. And along with authority will come, of their own accord, all these blessings, for they follow in the footsteps of the authority that pursues you. Thus all blessings will pursue you without you turning after them, and they will overtake you because of the authority. For through it, you will acquire all the blessings of all the nations of the earth, because what a servant acquires, his master acquires.
