(Ibid. 4) "For the L-rd will bless you in the land." Scripture hereby apprises us that the blessing inheres only in the land.
"which the L-rd your G-d gives to you to inherit" — so that you inherit it.
(Devarim 15:5) "Only if you hearken to the voice of the L-rd your G-d": From here they stated: If a man hearkens but a little, he is given to hear much. If he hearkens to the words of Torah, he is given to hear the words of the scribes.
