in , was when one said, "It is incumbent upon me to bring a burnt-offering" (without specifying a particular animal). And a freewill-offering was when one said, "This animal shall serve as a burnt-offering" (specifying a particular animal). In the case of vow offerings, one was responsible for replacement of the animal if the animal died or was stolen; but in the case of freewill obligations, one was not held responsible for the animal's replacement if the specified animal died or was stolen.

Ben Zoma interpreted the words "neither shall you do this in your land" in to forbid castrating even a dog (an animal that one could never offer as a sacrifice).

But Rav Dimi taught that if there is such a decree, one must incur martyrdom rather
