real reason is rather this, that the creation proceeds throughout from the lower to the higher; and in this ascending scale the fishes occupy to a great extent a lower place in the animal economy than birds, and both water animals and birds a lower place than land animals, more especially the mammalia. Again, it is not stated that only a single pair was created of each kind; on the contrary, the words, “let the waters swarm with living beings,” seem rather to indicate that the animals were created, not only in a rich variety of genera and species, but in large numbers of individuals. The fact that but one human being was created at first, by no means warrants the conclusion that the animals were created singly also; for the unity of the human race has a very different signification from that of the so-called animal species. - (Gen 1:22). As animated beings, the water animals and fowls are endowed, through the divine blessing, with the power to be fruitful and multiply. The word of blessing was the actual communication of the capacity to propagate and increase in numbers.
verses 24-31
The Sixth Day. - Sea and air are filled with living creatures; and the word of God now goes forth to the earth, to produce living beings after their kind. These are divided into three classes. בּהמה, cattle, from בהם, mutum, brutum esse, generally denotes the larger domesticated quadrupeds (e.g., Gen 47:18; Exo 13:12, etc.), but occasionally the larger land animals as a whole. רמשׂ ( the creeping) embraces the smaller land animals, which move either without feet, or with feet that are scarcely perceptible, viz., reptiles, insects, and worms. In Gen 1:25 they are distinguished from the race of water reptiles by the term האדמה ארץ חיתו (the old form of the construct state, for הארץ חיּת), the beast of the earth, i.e., the freely roving wild animals.
“ After its kind:” this refers to all three classes of living creatures, each of which had its peculiar species; consequently in Gen 1:25, where the word of God is fulfilled, it is repeated with every class. This act of creation, too, like all that precede it, is shown by the divine word “good” to be in accordance with the will of God. But the blessing pronounced is omitted, the author hastening to the account of the creation of man, in which the work of creation culminated. The creation of man does not take place through a word addressed by God to the earth, but as the result of the divine decree, “ We will make man in Our
