Overlapping oaths, the definition of שבועת שוא, and whether an oath follows the swearer's private meaning
Overview
The amud opens by finishing a case of two overlapping oaths. A man swore not to eat ten, then swore not to eat nine. He ate nine and brought a קרבן. After that, the tenth is only a חצי שיעור, so it carries no new קרבן. Then a new משנה defines a שבועת שוא, an empty oath. It covers swearing against an obvious fact, swearing about something impossible, and swearing not to testify or not to keep a מצוה. Taken on purpose, it earns מלקות. Taken by mistake, there is no penalty. In the גמרא, עולא says a fact counts as obvious once three people know it. אביי and רבא explain the odd wording 'if I did not see a flying camel.' רבינא then asks whether an oath follows the swearer's private meaning. Two proofs are pushed away: the court's warning before an oath, and משה's warning to ישראל. The גמרא ends by showing why משה needed to say whose meaning the oath followed.
Opening lines
וְאָכַל תְּאֵנִים וְהִפְרִישׁ קׇרְבָּן,
and he ate figs and set aside an offering,
וְאַחַר כָּךְ אָכַל עֲנָבִים לְחוֹדַיְיהוּ –
and afterward he ate grapes by themselves —
הָוְיָא לְהוּ עֲנָבִים חֲצִי שִׁיעוּר,
the grapes are a half-measure,
וְאַחֲצִי שִׁיעוּר לָא מִיחַיַּיב קׇרְבָּן.
and for a half-measure he is not liable to an offering.
