He sends forth springs in the valleys; they flow between the mountains; they give drink to every beast of the field; the wild donkeys quench their thirst.  Beside them the birds of the heavens dwell; they lift up their voices among the branches.  He waters the mountains from His upper chambers; the earth is satisfied with the fruit of his works.  He causes the grass to grow for the cattle, and vegetation for the labor of man, so that he may bring forth food from the earth.   Psalm 104:10-14
