I think the gist of this line is something like; No one of the Achaeans will eagerly obey the words of Agamemnon who is clothed in shamelessness, and crafty.
I don't understand why Agamemnon is in the dative case.
pei/qomai takes an object in the dative, that explains e)/pesin.
They are the words of Agamemnon, so why is agame/mnoni dative instead of genitive?
