Genesis 1:21

And God created great whales - התנינם הגדלים hattanninim haggedolim. Though this is generally understood by the different versions as signifying whales, yet the original must be understood rather as a general than a particular term, comprising all the great aquatic animals, such as the various species of whales, the porpoise, the dolphin, the monoceros or narwal, and the shark. God delights to show himself in little as well as in great things: hence he forms animals so minute that 30,000 can be contained in one drop of water; and others so great that they seem to require almost a whole sea to float in.

Created. - Here the author uses this word for the second time. In the selection of different words to express the divine operation, two considerations seem to have guided the author's pen - variety and propriety of diction. The diversity of words appears to indicate a diversity in the mode of exercising the divine power. On the first day Genesis 1:3 a new admission of light into a darkened region, by the partial rarefaction of the intervening medium, is expressed by the word "be." This may denote what already existed, but not in that place. On the second day Genesis 1:6-7 a new disposition of the air and the water is described by the verbs "be" and "make." These indicate a modification of what already existed. On the third day Genesis 1:9, Genesis 1:11 no verb is directly applied to the act of divine power. This agency is thus understood, while the natural changes following are expressly noticed. In the fourth Genesis 1:14, Genesis 1:16-17 the words "be," "make," and "give" occur, where the matter in hand is the manifestation of the heavenly bodies and their adaptation to the use of man. In these cases it is evident that the word "create" would have been only improperly or indirectly applicable to the action of the Eternal Being. Here it is employed with propriety; as the animal world is something new and distinct summoned into existence. It is manifest from this review that variety of expression has resulted from attention to propriety.

Great fishes. - Monstrous crawlers that wriggle through the water or scud along the banks.

Every living, breathing thing that creeps. - The smaller animals of the water and its banks.

Bird of wing. - Here the wing is made characteristic of the class, which extends beyond what we call birds. The Maker inspects and approves His work.

1:20-23 Each day hitherto hath produced very excellent beings, but we do not read of the creation of any living creature till the fifth day. The work of creation not only proceeded gradually from one thing to another, but advanced gradually from that which was less excellent, to that which was more so. 'Twas on the fifth day that the fish and fowl were created, and both out of the waters. Observe, 1. The making of the fish and fowl at first. Genesis 1:20,21 God commanded them to be produced, he said, Let the waters bring forth abundantly - The fish in the waters, and the fowl out of them. This command he himself executed, God created great whales, etc.-Insects which are as various as any species of animals, and their structure as curious, were part of this day's work, some of them being allied to the fish, and others to the fowl. Notice is here taken of the various species of fish and fowl, each after their kind; and of the great numbers of both that were produced, for the waters brought forth abundantly; and in particular of great whales the largest of fishes, whose bulk and strength, are remarkable proofs of the power and greatness of the Creator. Observe, 2, The blessing of them in order to their continuance. Life is a wasting thing, its strength is not the strength of stones; therefore the wise Creator not only made the individuals, but provided for the propagating of the several species, Genesis 1:22.

God blessed them, saying, Be fruitful, and multiply — Fruitfullness is the effect of God's blessing, and must be ascribed to it; the multiplying of the fish and fowl from year to year, is still the fruit of this blessing here.
