Thou crownest the year - A full and plentiful harvest is the crown of the year; and this springs from the unmerited goodness of God. This is the diadem of the earth; עטרת ittarta , Thou encirclest, as with a diadem. A most elegant expression, to show the progress of the sun through the twelve signs of the zodiac, producing the seasons, and giving a sufficiency of light and heat alternately to all places on the surface of the globe, by its north and south declination (amounting to 23° 28' at the solstices) on each side of the equator. A more beautiful image could not have been chosen; and the very appearance of the space termed the zodiac on a celestial globe, shows with what propriety the idea of a circle or diadem was conceived by this inimitable poet.
Thy paths drop fatness - מעגליך magaleycha , "thy orbits." The various planets, which all have their revolutions within the zodiacal space, are represented as contributing their part to the general fructification of the year. Or perhaps the solar revolution through the twelve signs, dividing the year into twelve parts or months, may be here intended; the rains of November and February, the frosts and snows of December and January, being as necessary for the fructification of the soil, as the gentle showers of spring, the warmth of summer, and the heat and drought of autumn. The earth's diurnal rotation on its axis, its annual revolution in its orbit, and the moon's course in aecompanying the earth, are all wheels or orbits of God, which drop fatness, or produce fertility in the earth.
