The mishnas (mishnayot) are devoted in the main to an exact definition of the rules of procedure in the case of a wife who was either actually or supposedly unfaithful. The mishnas discuss other rituals in which speech is a key component, such as egla arufa, breaking the heifer's neck; Hakheil, the Jewish King's septa-annual public Torah reading; and the Blessings and Curses of Mount Gerizim and Mount Ebal.
