For, behold, I will send serpents, cockatrices, among you, which will not be charmed, and they shall bite you, saith the LORD.
I - Yahweh.
Cockatrices - basilisks (Isaiah 11:8), i:e., enemies whose destructive power no means, by persuasion or otherwise, can counteract. Serpent charmers in the East entice serpents by music, and by a particular pressure on the neck render them incapable of darting (Psalms 58:4-5).
