ἄτερ [page 89]
For this (originally) poetic word which is found in the Grk Bible only 2Ma_12:15 , Luk_22:6 and Luk_22:35 , cf. Priene 109 .104 ( c. B.C. 120) ἄτερ ὀψωνίον , without salary. It occurs in P Oxy VI. 936 .18 (iii/A.D., a rather uneducated letter) ὁ ἠπητὴς λέγει ὅτι οὐ δίδω οὔτε τὸν χαλκὸν οὔτε τὸ φαινόλιν ἄτερ Ἰούστου , the cobbler says that he will not give up either the money or the cloak without Justus (Edd.). Cf. also P Leid W ii. 12 ( Apocrypha Moοsis ) ἄτερ γὰρ τούτων (the ω corrected from ο ) ὁ εὸς ( l. θεὸς ) οὐκ ἐπακούσεται . To the references in the Lexicons may be added Vettius Valens pp. 136 .9 , 271 .9 , 341 .3 , and Cleanthes hymn. Orph. 68, 8.
