“Only let us recognize the purpose of the evil. Why have the crops withered, our storehouses been emptied, the pastures of our flocks failed, the fruits of the earth been withheld and the plains been filled with shame instead of such fatness? Why have valleys lamented and not abounded in corn, the mountains not dropped sweetness, as they shall do hereafter to the righteous, but been stripped and dishonored and received on the contrary the curse of Gilboa? The whole earth has become as it was in the beginning, before it was adorned with its beauties. "You visited the earth and made it to drink," but the visitation has been for evil and the draught destructive.”

“its furrows Heb. תלמיה. They are the rows of the plowshare. To sate Heb. רוה, like לרוה. to afford pleasure to its troops Heb. נחתגדודה, like לְנַחֵתגְדוּדֶהָ, to give rest to its troops. To afford pleasure to its creatures, You dissolve it with drops of rain. You dissolve it Heb. תמגגנה, an expression of melting.”

“Thou crownest the year with thy goodness,.... The whole circling year, from one end of it to the other; particularly that season of it when the harvest is gathered in; the seed being sown, the earth watered, the springing of it blessed, and the corn brought to perfection, the year is crowned with a plentiful harvest: this may denote the acceptable year of the Lord, the year of the redeemed, the whole Gospel dispensation, Isa 61:2; in certain seasons and periods of which there have been great gatherings of souls to Christ; at the first of it multitudes were converted in Judea, and in the Gentile world, which were the first fruits of the Spirit; and in all ages there have been more or less instances of this kind; and in the latter day there will be a large harvest, when the Jews will be converted, and the fulness of the Gentiles brought in; and thy paths drop fatness; the heavens, as Jarchi interprets it; or the clouds, as Kimchi; which are the chariots and horses of God, in which he rides, and are the dust of his feet, Psa 104:3, Nah 1:3; and these drop down rain upon the earth, and make it fat and flourishing; and may mystically design the administration of the Gospel, and the administration of ordinances; which are the paths in which the Lord goes forth to his people, and directs them to walk in, and in which he meets them with a fulness of blessings, and satisfies them as with marrow and fatness.”

“H. P. " Thou settlest the furrows thereof." Sulcos was in the version used by St. Augustin. St Jerome translates in the same way. The effect of the rain showers on the earth is indicated.”
“H. P. " Thou makest it soft with showers. Thou blessest the springing thereof." St. Jerome gives the same meaning, but in the imperative mood.”
