87.81 · Status · Slave, Free
fellow slave one who is a fellow slave or a slave alongside another slave In some languages there is a very strong negative connotation in any word meaning ‘slave,’ for it may suggest ‘vile person’ or even ‘foreigner,’ since in a number of areas only foreigners were made slaves. It may therefore be necessary to use a term for slave which is more or less equivalent to ‘servant,’ ‘one who works without pay,’ ‘one who must work without pay,’ or ‘bondservant.’

Moulton & Milligan — Vocabulary of the Greek NT
σύνδουλος, “‘a fellow-slave’’: BGU IV. 11412? (B.c. 13) παρὰ (cf. Jannaris Gr. 1619>) τὸν σύνδουλόν σου Kal συνεξελεύθερον, ““ except your fellow-slave and fellow-freedman,”’ and 76.8, P Lond 1213(a)4(a.D. 65-66) (= III. p. 121) μέτρησον Σόφῳ συνδούλῳ, 2. 157 2.8 (ii/A.D.?) (= 11. p. 255) ἴδετε τ[ὴ]ν οἰκίαν tod συνδούλ[ο]υ σου, and the late BGU II. 547* (Byz.) μὴ ὀχλῆσαι τῷ συνδούλῳ μου τῷ εὐλαβ(εστάτῳ) Πέτρῳ τῷ διακόνῳ. The distinction drawn by Moeris (p. 273) that ὁμόδουλος is Attic and σύνδουλος Ifellenistic cannot be maintained : see Headlam’s note ad Herodas V. 56.
