ὄγκος — ónkos
ὄγκος, ὀγδου, ὁ (apparently from ἘΓΚΩ, ἐνεγκεῖν, equivalent to φόρτος, see Buttmann, Lexil. i. 288ff (Fishlake's translation, p. 151f), whatever is prominent, protuberance, bulk, mass, hence), a burden, weight, encumbrance: Heb 12:1. (In many other uses in Greek writings of all ages.) [SYNONYMS: ὄγκος, βάρος, φορτίον: βάρος refers to weight, o. to bulk, and either may be oppressive (contra Tittmann); βάρος a load in so far as it is heavy, φορτίον a burden in so far as it is borne; hence, the φορτίον may be either 'heavy' (Mat 23:4; Sir 21:16), or 'light' (Mat 11:30).]
