신명기 28:12의 주석

יפתח ה׳ לך את אוצרו הטוב, "G'd will open for you His store of goodness, etc." From this point on until the end of verse 13 the Torah describes the reward for fulfilling the positive commandments. This is why verse 13 concludes with the words "if you listen to the commandments of the Lord your G'd." The channels which G'd employs to direct the outpourings of His goodness to earth are activated through performance of commandments rather than through the passive refraining from violating negative commandments.

V. 12. יפתח וגו׳, darum lässt Gott selbst die deine Bodenblüte bedingenden Witterungserscheinungen mit einer Regelmäßigkeit eintreten, die Sein unmittelbares Einwirken konstatieren, und gibt dir einen solchen Überfluss, dass, wenn anderwärts Mangel ist, du mit deinem Überfluss aushelfen musst, nie aber in die entgegengesetzte Lage kommst, und so

והלוית גוים רבים, “and you will lend to many nations;” to nations who were plagued with crop failures or storage problems in their barns.
