5.39
If this is so, I, for my part, believe that if you undertake a campaign, you would not be giving aid to the Lacedaemonians so much as to your own selves. For to have the Thebans, who are unfriendly to you and dwell on your borders, become leaders of the Greeks, would prove much more grievous to you, I think, than when you had your antagonists far away. Furthermore, you would aid yourselves with more profit if you should do so while there are still people who would fight on your side, than if they should perish first and you should then be compelled to enter by yourselves upon a decisive struggle with the Thebans.
5.40
Now if any are fearful that in case the Lacedaemonians escape this time, they may again in the future cause you trouble, take thought of this, that it is not those whom one benefits, but those whom one injures, of whom one has to fear that they may some day attain great power. And you should bear in mind this likewise, that it is meet both for individuals and for states to acquire a goodly store in the days when they are strongest, in order that, if some day they become powerless, they may draw upon their previous labours for succour.
