“Achaemenes,” Xerxes answered, “I think that you speak well, and I will do as you counsel. Despite the fact that your advice is better than his, Demaratus does say what he supposes to be most serviceable to me,

for assuredly I will never believe that he is no friend to my cause. I believe this of him because of all that he has already said and by what is the truth, namely, that if one citizen prospers, another citizen is jealous of him and shows his enmity by silence, and no one, (except if he has attained the height of excellence; and such are seldom seen) if his own townsman asks for counsel, will give him what he thinks to be the best advice.

If one stranger prospers, however, another stranger is beyond all men his well-wisher and will, if he is asked, impart to him the best counsel he has. It is for this reason that I bid you all to refrain from maligning Demaratus, seeing that he is a stranger and a friend.”
