Psalms 104:9

Psalms 104:9. Thou hast set a bound that they may not pass over; that they turn not again to cover the earth.

Jehovah puts the bit of sand into the mouth of the sea, and it comes no farther than its appointed bounds. Now you must suppose the psalmist is leaving the crowded streets, and the dingy, dusty, smoky haunts of men, and flying, on the wings of his gratitude and praise, away into the quiet of the fertile country.
