Moulton & Milligan — Vocabulary of the Greek NT
ὁρκωμοσία [page 458]
This rare word = taking of an oath with reference to the whole action is confined in the NT to Heb_7:20-21 ; Heb_7:28 . For the neut. ὁρκωμόσιον see Syll 592 (= .3 1007) .29 (B.C. 130 100), and for the plur. OGIS 229 .82 (iii/B.C.) τὰ δὲ ἱερεῖα τὰ εἰς τὰ [ὁρ ]κωμόσια ἐν Σμύρνηι [δότω ὁ ταμίας Καλ ]λῖνος . The easy transference to 1st decl. is suggested by such analogies as ἀντωμοσία . For ὁρκωμότης see P Grenf I. 11 ii. 17 (B.C. 157), and cf. Preisigke Fachwφrter s.v.
