Isaiah 58:14

14 Then you will find joy in your relationship to the Lord, ^{▼▼ For a parallel use of the phrase “find joy in” (Hitpael of עָנַג [’anag] followed by the preposition עַל [’al]), see Ps 37:4.}
and I will give you great prosperity, ^{▼▼ Heb “and I will cause you to ride upon the heights of the land.” The statement seems to be an allusion to Deut 32:13, where it is associated, as here, with God’s abundant provision of food.}
and cause crops to grow on the land I gave to your ancestor Jacob.” ^{▼▼ Heb “and I will cause you to eat the inheritance of Jacob your father.” The Hebrew term נַחֲלָה (nakhalah) likely stands by metonymy for the crops that grow on Jacob’s “inheritance” (i.e., the land he inherited as a result of God’s promise).}
Know for certain that the Lord has spoken. ^{▼▼ Heb “for the mouth of the Lord has spoken.” The introductory כִּי (ki) may be asseverative (as reflected in the translation) or causal/explanatory, explaining why the preceding promise will become reality (because it is guaranteed by the divine word).}
