5.13 · Foods and Condiments · Food
without yeast, not having yeast, unleavened pertaining to the absence of yeast The phrase ‘unleavened bread’ may be rendered as ‘bread made without yeast’ or ‘bread which does not rise.’ Perhaps a more difficult problem is involved in the relationship of ‘days’ to ‘unleavened bread,’ and accordingly, the expression ‘the days of Unleavened Bread’ may be rendered as ‘the days when people ate bread that had no yeast.’ Except for 1CO 5:7, in which ἄζυμος occurs in a highly figurative passage referring to pure and true life, this term is used exclusively in reference to the feast or festival of Unleavened Bread.
