The cockatrice' den - This is supposed, both by the Targum and by Kimchi, to mean the pupil of this serpent's eye. "When," says Kimchi, "he is in the mouth of his den, in an obscure place, then his eyes sparkle exceedingly: the child, seeing this, and supposing it to be a piece of crystal, or precious stone, puts forth his hand to take it.
