azumos describes bread and festival observance marked by the absence of leaven, and frames sincerity and truth against old leaven.

The term is used chiefly in the designation of a festival or its days, in contexts joined to Passover and preparation for its meal. In 1 Corinthians, it occurs in a contrast between old leaven and a new lump, and with bread characterized by sincerity and truth rather than malice and evil.

1. Festival and its designated days · dominant

   The genitive plural neuter form occurs in references to the days or festival approaching, passing, or arriving: in Acts 12:3 the APB renders "the days of unleavened bread," and in Acts 20:6 it places sailing after those days. In Luke 22:1, Luke 22:7, Mark 14:12, and Matthew 26:17, the clauses connect the designation with Passover and preparation or sacrifice of the Passover lamb.

2. Bread imagery in a moral contrast · occasional

   In 1 Corinthians 5:7, the nominative plural masculine form appears in the appeal to become a new lump after the old leaven is removed. In 1 Corinthians 5:8, the dative plural neuter form occurs in the clause the APB renders "with the unleavened bread of sincerity and truth," set against old leaven, malice, and evil.

In the Anselm Project Bible: The APB commonly presents the term in the fixed wording "Unleavened Bread" or "unleavened bread," while Acts 12:3 and Acts 20:6 render the surrounding expression as "days of unleavened bread." These renderings show the verse-level presentation rather than a separate English equivalent for every form.
