Unabridged English Text of this Mitzvah »

> The 94th mitzvah is that we are commanded to fulfill every verbal obligation we have taken upon ourselves, whether an oath, a vow, a korban,;) etc.

>

>

> The source of this commandment is G‑d's statement,;) "You shall be careful to carry out whatever you say."

>

>

> Although our Sages have split up this verse and explained each word separately as referring to something different, the general meaning of everything they say is: it is a positive commandment for a person to fulfill every verbal obligation he has taken upon himself, and a prohibition not to do so. This will be explained in our discussion of the prohibitions.;)

>

> The Sifri says, "The verse, 'Whatever you say,' constitutes a positive commandment." You find it obvious that the words, "whatever you say" by themselves have no meaning whatsoever. The intention [of the Sifri] is therefore as I explained above — that the plain meaning of the verse is that a person is obligated to carry out his verbal commitments.

>

>

> This commandment is stated a second time in G‑d's statement,;) "A person must fulfill all he has verbally said."

>

>

> The details of this mitzvah — i.e., how exactly the person must fulfill his obligation, and how he can be released [from his obligation] when in doubt regarding his statement — are explained in a number of passages in Sh'vuos, Nedarim, the end of Menachos, as well as in Kinim.
