It is Odysseus himself, disguised as a beggar, who issues this warning:

Herdsman, I make you out to be no coward
and no fool: I can see that for myself.
So let me tell you this. I swear by Zeus
all highest, by the table set for friends,
and by your king's hearthstone to which I've come,
Odysseus will return. You'll be on hand
to see, if you care to see it,
how those who lord it here will be cut down."
