14 Then you can seek the favor of Hashem. I will set you astride the heights of the earth, And let you enjoy the heritage of your father Yaakov— For the mouth of Hashem has spoken.

58:14 The heritage of your father Yaakov
Yeshayahu describes the beautiful rewards for following Hashem’s commandments. Those who do so will delight in the heritage of Yaakov. And what is heritage of Yaakov? As it says in Sefer Bereishit, Hashem promised Yaakov that the “the ground upon which you are lying (i.e. the Land of Israel) I will assign to you and to your offspring” (Geneis 28:13).
