The rabbis note examples of this rule regarding shevuot, oaths. Regarding oaths that are utterances, there are two that are four:
- "I will eat" "I will not eat" actually include utterances of, "I ate" and "I did not eat"
- 'Awareness of defiling the Temple' includes awareness of ritual impurity before eating sacrificial food and before entering the Temple; this actually includes awareness of the ritual purity of sacrificial food and awareness that one was in a holy place
- Carrying out on Shabbat includes two that are four: a poor person or by a homeowner; bringing in by a poor person or by a homeowner
- Identification of leprous marks are "two that are four" with a wool-white leprous mark and a snow-white leprous mark; these include similar marks beside each of these marks
The rabbis argue about whether or not one should be punished with flogging for the violation of a prohibition which does not involve an action. Reish Lakish clarifies that one is not flogged in this case because one cannot be forewarned with certainty.
