Vows and Oaths

To vow or not to vow- In our first class, we will survey the rabbinic sources which discourage all vows and oaths.

Defining Vows (Nedarim)-Today we will complete the definition of vows (nedarim) and then begin the definition of oath (shevuah). Only by defining these concepts can we determine what is and what is not a binding vow or oath.

The Terminology of a Vow or Oath I- Today we finish the basic definition of oaths. Then we will start the discussion of the actual words that must be spoken for an oath or vow to be valid. Must the name of G-d be used? Is use of the work “vow” or “oath” by itself sufficient? We will also discuss lashon kaful, repeating oneself to make an oath or vow.

The Terminology of a Vow or Oath II-Today we will examine specific examples of vows in everyday situations, analyzing how the poskim apply the basic principles we have learned to real cases.

The Terminology of a Vow or Oath III- You can prohibit others from using your property by uttering a vow. Once the vow has been uttered, what exactly becomes prohibited? May others look at your property? May they think about it? Talk about it? Today we will examine the opinions of the great rabbis defining איסור הנאה, the prohibition to use someone’s property.

Using Incorrect Terminology- Today we will deal with one last example of vows and oaths: In our prayers we often promise to do good. Are these promises binding oaths? Then we will turn to the question of incorrect formulation in oaths and vows. Cases like these are very common: We know that vows (נדרים) apply to objects and oaths (שבועות) apply to actions. What is the status of a vow (נדר) to do something or an oath (שבועה) to prohibit an object?
