(9) A bound.--It is striking to observe what a deep impression their little line of coast, the barrier which beat off the waves of the Mediterranean, made on the Hebrew mind. The sea was an object of dread. Or if dread passes into reverent wonder, as in Psalm 104:25-26, it ends there; the Jew never took delight in the sea. Hence, the coast has for him only one purpose and suggestion. It is not for enjoyment or recreation, or even for uses of commerce. It is simply the defence set by God against the hostile waters.

Verse 9. - Thou hast set (or, didst set) a bound that they may not (rather, might not) pass over (comp. Job 38:10, 11; Jeremiah 5:22). The Deluge is for the time beyond the ken of the poet, who is singing God's greatness in nature, and in the general laws under which he has placed it. Neither turn again to cover the earth. This law, once Broken by the miracle of the Deluge, was thenceforth made absolute and inviolable (Genesis 9:15).

104:1-9 Every object we behold calls on us to bless and praise the Lord, who is great. His eternal power and Godhead are clearly shown by the things which he hath made. God is light, and in him is no darkness at all. The Lord Jesus, the Son of his love, is the Light of the world.Thou hast set a bound, that they may not pass over,.... The Targum adds,

"to the rolling waves of the sea.''

Set doors with bolts and bars, cliffs, rocks, and shores: and, what is more surprising, sand, which is penetrable, flexible, and moveable, is set as a perpetual bound to the raging ocean and its waves, which they cannot pass over: see Job 38:8. So the Lord has set a bound to the proud waters of afflictions, and says, Thus far shall ye go, and no farther; and to the life of man, which he cannot exceed, Job 14:5. But he has given man a law, as a rule to walk by, as the boundary of his conversation, and this he transgresses; in which he is less tractable than the raging sea and its waves. That they turn not again to cover the earth; as they did when it was first made, Psalm 104:6 that is, not without the divine leave and power; for they did turn again and cover the earth, at the time of the flood; but never shall more. Some think there is no need to make this exception; since this was written after the flood, and when God had swore that the waters should no more go over the earth, Isaiah 54:9.
