Isaiah 11:8

And the sucking child shall play on the hole of the asp... — The description culminates in the transformation of the brute forms which were most identified with evil. As it is, the sight of a child near the hole of the asp (the cobra) or cockatrice (better, perhaps, basilisk, the great viper), would make its mother scream with terror. There was still “enmity between the seed of the woman and the seed of the serpent” (Genesis 3:15), but in the far-off reign of the Christ even that enmity should disappear, and the very symbols of evil, subtle, malignant, venomous, should be reconciled to humanity. Some critics translate the last clause, “shall stretch out his hand to the eye-ball of the basilisk” as if alluding to the power of fascination commonly assigned to it.
