Who giveth rain upon the earth - In the previous verse, Eliphaz had said, in general, that God did wonderful things - things which are fitted to lead us to put our trust in him. In this and the succeeding verses, he descends to particulars, and specifies those things which show that God is worthy to be confided in. This enunciation continues to Job 5:16, and the general scope is, that the agency of God is seen everywhere; and that his providential dealings are adapted to impress man with elevated ideas of his justice and goodness. Eliphaz begins with the rain, and says that the fact that God sends it upon the earth was fitted to lead man to confide in him. He means, that while the sun, and moon, and seasons have stated times, and are governed by settled laws, the rain seems to be sent directly by God, and is imparted at such times as are best. It is wholly under his control, and furnishes a constant evidence of his benevolence. Without it, every vegetable would dry up, and every animal on the earth would soon die. The word earth here refers probably to the cultivated part of the earth - the fields that are under tillage. Thus, Eichhorn renders it, Angebauten Feldern. On the interest which the phenomena of rain excited among the ancient sages of Idumea, and the laws by which it is produced, see Job 37:6, note; Job 37:15-16, note; Job 38:22-28, note.
And sendeth waters - That is, showers.
Upon the fields - Margin, “out-places.” Hebrew חוצוּת chûtsôt - out of doors, outside, abroad, meaning the fields out of cities and towns. Eichhorn renders it, “the pastures,” auf Triften. The meaning is, that the whole country is watered; and the fact that God gives rain in this manner, is a reason why we should put confidence in him. It shows that he is a benevolent Being, since it contributes so essentially to human life and happiness, and since no other being but God can cause it.
