Unleavened
UNLEAVENED (Heb. matstsâh, sweet, Gr. azymos). A word often found in both Testaments, usually in a literal but sometimes in a figurative sense. When used literally, it refers to bread made without any fermented dough (yeast, leaven) or to the Passover Feast, when only unleavened bread could be used. When used figuratively, it means “unmixed” (1Cor.5.7-1Cor.5.8 kjv; niv reads “without yeast”).
