עָר֤וּם רָאָ֣ה רָעָ֣ה נִסְתָּ֑ר פְּ֝תָאיִ֗ם עָבְר֥וּ נֶעֱנָֽשׁוּ׃

ונזיר שנטמא – as it is written (Numbers 6:9): “If a person suddenly dies near him,” – פתע/aforethought – this is inadvertently, and similar it says (umbers 35:22): “Or if he pushed him without malice aforethought,” -פתאום/suddenly – this is willful, but there is no punishment other than through willful [transgression].
