oporteat

-Sed sumne ego stultus, qui rem curo publicam Ubi sunt magistratus, quos curare oporteat? and taken as a whole, we can hardly imagine a comedy politically more tame than was that of Rome in the sixth century. The oldest Roman comic writer of note, Gnaeus Naevius, alone forms a remarkable exception.

Theodor Mommsen - The History of Rome (Volumes 1-5)

Ego ac tu simplicissime inter nos hodie loquimur; ceteri libentius cum fortuna nostra, quam nobiscum. Nam suadere principi quod oporteat multi laboris: adsentatio erga principem quemeunque sine adfectu peragitur." It will be seen from this literal version of his text, that, notwithstanding his epigrammatic brevity, Tacitus writes with a precision of thought that leaves nothing to be supplied.

John Wilson Ross - Tacitus and Bracciolini : The Annals Forged in the XVth Century

Distinctio poenarum ex delicto: proditores et transfugas arboribus suspendunt; ignavos et imbelles et corpore infames coeno ac palude, injecta insuper crate, mergunt. Diversitas supplicii illuc respicit, tanquam scelera ostendi oporteat, dum puniuntur, flagitia abscondi.
