Thou openest thine hand - By the mere opening of the hand all needful gifts are bestowed on the creatures dependent on thee. The same words are found in Psalms 104:28; see the notes at that passage.
And satisfiest the desire of every living thing - All kinds of creatures - people, fowls, beasts, fishes, insects - the innumerable multitudes that swarm on the earth, in the air, in the waters. In Psalms 104:28, it is, “They are filled with good.” The meaning is essentially the same. Of course this is to be taken in a general sense. It cannot mean that absolutely no one ever needs, or ever perishes from want, but the idea is that of the amazing beneficence and fullness of God in being able and willing to satisfy such multitudes; to keep them from perishing by cold, or hunger, or nakedness. And, in fact, how few birds perish by hunger; how few of the infinite number of the inhabitants of the sea; how few animals that roam over deserts, or in vast plains; how few people; how few even of the insect tribes - how few in the world revealed by the microscope - the world beneath us - the innumerable multitudes of living things too small even to be seen by the naked eye of man!
