Non-Jews do not have nezirus. Women and slaves do have nezirus. There is [an aspect of greater] stringency applying to women than to slaves, for one can force his slave [to violate his nezirus], but he cannot force his wife. There is [an aspect of greater] stringency applying to slaves than to women, for one can revoke his wife’s vows, but he cannot revoke his slave’s vows.  [If] he revoked for his wife —- he has revoked permanently; [if] he revoked for his slave —- [if] he went free, he completes his nezirus.  [If the slave] passed from his [masteR’s] presence —- R’ Meir says: He may not drink. But R’ Yose says: He may drink.
