Philopoemen (15.5-15.6)

And in the second place, Timolaüs himself, when he came to Megalopolis, having been entertained at the house of Philopoemen, and having learned thoroughly how dignified he was in his converse with others, how simple his ways of living, and how his character was nowhere to be approached and much less easy to be overcome by bribes, held his peace about the gift of money, and after giving some other excuse for his visit to him, went back home. And when he was sent a second time on the same errand, he did as before.

On his third visit, however, he at last got so far as to acquaint Philopoemen with the earnest desire of his city. Then Philopoemen, who was pleased by what he heard, went in person to Sparta, and counselled the people there not to try to bribe good men who were their friends, and by whose virtues they could profit without payment of money, but rather to buy up and corrupt the bad men who were ruining the city by their factious conduct in the assembly, to the end that such might have their mouths stopped in consequence of their venality, and so he less annoying to their fellow-citizens; for it was better, he said, to take away freedom of speech from their enemies rather than from their friends. Such was his splendid spirit in matters of money.
