quot servi, tot hostes

Latin

Literally, “as many slaves, so many enemies”. Most likely a simplification of earlier proverbs such as totidem hostēs esse quot servōs (“to be just as many enemies as slaves”) in Seneca the Younger.^[1]^[2]

(Classical Latin) IPA^(key): /kʷot ˈser.u̯iː tot ˈhos.teːs/, [kʷɔt̪ ˈs̠ɛru̯iː t̪ɔt̪ ˈhɔs̠t̪eːs̠]
(modern Italianate Ecclesiastical) IPA^(key): /kwot ˈser.vi tot ˈos.tes/, [kwɔt̪ ˈsɛrvi t̪ɔt̪ ˈɔst̪es]

every slave is an enemy
- 1880, Sextus Pompeius Festus, edited by Karl Otfried Müller, Sexti Pompei Festi De verborum significatione quae supersunt cum Pauli Epitome, Leipzig, page 261/1:
  Quot servi, tot hostes, in proverbio est, de quo Sinnius Capito existomat errorem hominibus intervenisse praepostere plurimis enuntiantibus.
  "As many slaves, so many enemies," is in a proverb, of which Sinnius Capito reckons an error by humans has intervened irregularly through many tellings.
