Thayer's Greek Lexicon
ἄζυμος, (ζύμη), Hebrew ξΗφΘΜδ, unfermented, free from leaven; properly: ἄρτοι Exo_29:2; Josephus, Antiquities 3, 6, 6; hence the neuter plural τά ἄζυμα, ξΗφΜεϊ, unleavened loaves; ἡ ἑορτή τῶν ἀζύμων, δΗξΗΜφΜεϊ ηΗβ, the (paschal) festival at which for seven days the Israelites were accustomed to eat unleavened bread in commemoration of their exit from Egypt (Exo_23:15; Lev_23:6), Luk_22:1; ἡ πρώτη (namely, ἡμέρα) τῶν ἀζύμων. Mat_26:17; Mar_14:12; Luk_22:7; αἱ ἡμέραι τῶν ἀζύμων. Act_12:3; Act_20:6; the paschal festival itself is called τά ἄζυμα, Mar_14:1 (cf. 1Es_1:10; 1Es_1:19; Winers Grammar, 176 (166); Buttmann, 23 (21)). Figuratively: Christians, if such as they ought to be, are called ἄζυμοι i. e. devoid of the leaven of iniquity, free from faults, 1Co_5:7; and are admonished ἑορτάζειν ἐν ἀζύμοις εἰλικρινείας, to keep festival with the unleavened bread of sincerity and truth, 1Co_5:8. (The word occurs twice in secular authors, viz. Athen. 3, 74 (ἄρτον) ἄζυμον, Plato, Tim., p. 74 d. ἄζυμος σάρξ flesh not yet quite formed (add Galen de alim. fac. 1, 2).)
