In Act IV, Scene 9, Elizabeth tells John Proctor that Rebecca Nurse "is one foot in heaven now. Naught may hurt her more." Proctor is trying to get the people who are accused of witchcraft to confess so that they will be pardoned. However, Rebecca, as Proctor realizes, will not confess to be a witch as he is contemplating doing himself. Instead, as Proctor says, Rebecca will "go like a saint." Rebecca is a devout and respected member of the Salem community. When Elizabeth says that Rebecca "is one foot in heaven," it does not exactly mean that she has "one foot in the grave." True, she will be executed soon, so in that sense, she has one foot in the grave. However, there is an additional meaning to the phrase "one foot in heaven," which is that Rebecca is so virtuous and devout that she is on her way to becoming a saint in heaven.
