They are joined one to another,.... One scale to another, or "a man in his brother" h: which may seem to favour the notion of the whale's teeth in the sockets, which exactly answer to one another; but the next clause will by no means agree with them;
they stick together, that they cannot be sundered: whereas they easily be, at least by the creature itself; but the scales of a crocodile are so closely joined and sealed together, that there is no parting them.
h איש באחיהו "vir in fratre suo"; Montanus.
