(Ibid.): "As the opening of a suit of armor shall it [its neck-opening] be for it, so that it not be torn." Why need the Torah add "as the opening of a suit of armor"? Is it not sufficient to have stated "And the mouth of its head shall be [folded over] within it. A border shall there be for its mouth"? It must intimate, then, that just as one dons armor for protection, that he not be harmed by the arrows shot at him, so, if one clamps shut his mouth, it affords him protection against his antagonist, and, in the end, it serves to silence him by giving him no answer. If he answered him, however, the quarrel would widen and he would come to blows, as it is written (Ibid. 21:18): "And if men quarrel, and a man strike his neighbor with stone or fist, etc." And the Holy One Blessed be He is also his Protector because of this, because "the earth depends upon him," as mentioned above.
