Any fish, either from salt water or fresh, might be eaten if it had both scales and fins. but no other creature that lives in the waters. Shellfish of all kinds, whether mollusks or crustaceans, and cetaceous animals, were therefore prohibited, as well as fish which appear to have no scales, like the eel; probably because they were considered unwholesome, and (under certain circumstances) found to be so.

Whatsoever hath fins and scales - Because these, of all the fish tribe, are the most nourishing; the others which are without scales, or whose bodies are covered with a thick glutinous matter, being in general very difficult of digestion.

These shall ye eat of all that are in the waters,.... In the waters of the sea, or in rivers, pools, and ponds; meaning fishes; for though some persons abstain from eating them entirely, as the Egyptian priests, as Herodotus (m) relates; and it was a part of religion and holiness, not with the Egyptians only, but with the Syrians and Greeks, to forbear eating them (n); and Julian (o) gives two reasons why men should abstain from fishes; the one because what is not sacrificed to the gods ought not to be used for food; and the other is, because these being immersed in the deep waters, look not up to heaven; but God gave the people of Israel liberty of eating them, under certain limitations:

whatsoever hath fins and scales, in the waters, in the seas, and in the rivers, them shall ye eat; some render it disjunctively, "fins or scales" (p); but as Maimonides (q) observes, whatsoever has scales has fins; and who also says, if a fish has but one fin and one scale, it was lawful to eat: fins to fishes are like wings to birds, and oars to boats, with which they swim and move swiftly from place to place; and scales are a covering and a protection of them; and such fishes being much in motion, and so well covered, are less humid and more solid and substantial, and more wholesome: in a spiritual sense, fins may denote the exercise of grace, in which there is a motion of the soul, Godward, Christward, and heavenward; and scales may signify good works, which adorn believers, and protect them from the reproaches and calumnies of men.

(cf. Deuteronomy 14:9 and Deuteronomy 14:10). Of water animals, everything in the water, in seas and brooks, that had fins and scales was edible. Everything else that swarmed in the water was to be an abomination, its flesh was not to be eaten, and its carrion was to be avoided with abhorrence. Consequently, not only were all water animals other than fishes, such as crabs, salamanders, etc., forbidden as unclean; but also fishes without scales, such as eels for example. Numa laid down this law for the Romans: ut pisces qui sqamosi non essent ni pollicerent (sacrificed): Plin. h. n. 32, c. 2, s. 10. In Egypt fishes without scales are still regarded as unwholesome (Lane, Manners and Customs).

These shall ye eat of all that are in the waters: whatsoever hath fins and scales in the waters, in the seas, and in the rivers, them shall ye eat.

11:9 Fins and scales - Both of them; such fishes being more cleanly, and more wholesome food than others. The names of them are not particularly mentioned, partly because most of them wanted names, the fish not being brought to Adam and named by him as other creatures were; and partly because the land of Canaan had not many rivers, nor great store of fish.

9. These shall ye eat . whatsoever hath fins and scales-"The fins and scales are the means by which the excrescences of fish are carried off, the same as in animals by perspiration. I have never known an instance of disease produced by eating such fish; but those that have no fins and scales cause, in hot climates, the most malignant disorders when eaten; in many cases they prove a mortal poison" [Whitlaw].

11:1-47 What animals were clean and unclean. - These laws seem to have been intended, 1. As a test of the people's obedience, as Adam was forbidden to eat of the tree of knowledge; and to teach them self-denial, and the government of their appetites. 2. To keep the Israelites distinct from other nations. Many also of these forbidden animals were objects of superstition and idolatry to the heathen. 3. The people were taught to make distinctions between the holy and unholy in their companions and intimate connexions. 4. The law forbad, not only the eating of the unclean beasts, but the touching of them. Those who would be kept from any sin, must be careful to avoid all temptations to it, or coming near it. The exceptions are very minute, and all were designed to call forth constant care and exactness in their obedience; and to teach us to obey. Whilst we enjoy our Christian liberty, and are free from such burdensome observances, we must be careful not to abuse our liberty. For the Lord hath redeemed and called his people, that they may be holy, even as he is holy. We must come out, and be separate from the world; we must leave the company of the ungodly, and all needless connexions with those who are dead in sin; we must be zealous of good works devoted followers of God, and companions of his people.
