Actually, here's one I posted a little over a year ago, whilst in France.
Tondere: To clip, to shear, to mow.
French: Tondre: To clip, to shear, to mow.
Ovid: Boni pastoris est tondere pecus, non deglubere.
The translation I like is: "A good shepherd shears his sheep; he doesn't flay them."
It's a nice line to remember right around tax time!
