Psalms 104:10

10. He sendeth the springs into the valleys The poet here suspends his direct notice of the “six days’ work,” to speak of the works of providence.

After the ocean, it is fit that he should speak of springs in the mountains and hills, for these proceed from the ocean through evaporation and the containing and carrying power of the atmosphere. Of this hydraulic system of nature the Hebrews had knowledge. Ecclesiastes 1:7; Genesis 2:6; Amos 9:6. נהלים , ( nehaleem,) generally means rivers, but sometimes wadys, or valleys. It may here take either sense. “He sendeth,” refers the origin and uses of springs and fountains directly to the act of God, who “sendeth” the waters of the ocean to the elevated lands of the continents to create fountains, which he causeth to flow down and irrigate the valleys, or to empty into the larger streams.
