Their venom is like that of a snake, like a deaf serpent that does not hear, that does not respond to the magicians, or to a skilled snake-charmer.

If the snake should bite before it is charmed, the snake charmer is in trouble.

The Lord says, "Yes indeed, I am sending an enemy against you that will be like poisonous snakes which cannot be charmed away. And they will inflict fatal wounds on you."
