Verse 7 Every kind of beasts - That is, every species of wild beasts, πασα φυσις θηριων, is tamed, i.e. brought under man's power and dominion. Beasts, birds, serpents, and some kinds of fishes have been tamed so as to be domesticated; but every kind, particularly των εναλιων, of sea monsters, has not been thus tamed; but all have been subjected to the power of man; both the shark and whale become an easy prey to the skill and influence of the human being. I have had the most credible information, when in the Zetland Isles, of the seals being domesticated, and of one that would pass part of his time on shore, receive his allowance of milk, etc., from the servants, go again to sea, and return, and so on.

For it is the same authority which establishes every commandment.

Jas 3:7

Fourth illustration, involving a proof of the terrible power of the tongue for evil. All kinds of wild animals, etc., can be tamed and have been tamed: the tongue cannot be. What a deadly power for evil must it therefore be! The famous chorus in Sophocles, ’Antigone,’ 1. 332, seq., Πολλὰ τὰ δεινὰ κοὐδὲν ἀνθώπου δεινότερον πέλει, is quoted by nearly all commentators, and affords a remarkable parallel to this passage. Every kind of beasts, etc.; literally, every nature (φύσις) of beasts … hath been tamed by man’s nature (τῇ φύσει τῇ ἀνθρωπίνῃ); Vulgate, omnis enim natura bestiarum … domita sunt a natura humana. With this fourfold enumeration of the brute creation ("beasts .. birds.., serpents … things in the sea"), cf. Gen 9:2, "The fear of you and the dread of you shall be upon all the beasts (θήρια) of the earth, upon all the fowls (πέτεινα) of the heavens, and upon all that moveth upon the earth, and upon all the fishes of the sea." Serpents (ἐρπετά) would be better rendered, as B.V., creeping things.

Verse 11. For he that said, Do not commit adultery, said also, Do not kill. That is, these are parts of the same law of God, and one is as obligatory as the other. If, therefore, you violate either of these precepts, you transgress the law of God as such, and must be held to be guilty of violating it as a whole. The penalty of the law will be incurred, whatever precept you violate. (+) "For he that said" or, "that law which said" (a) "Do not commit adultery, said also, Do not kill" Ex 20:13-14
