[If] one derived half a perutah’s worth of benefit [from a consecrated object] and deteriorated [it] by half a perutah, or he derived a perutah’s worth of benefit from one object and de- teriorated a different object by one perutah’s worth, he has not committed me’ilah until he derives one perutah’s worth of benefit and causes one perutah’s worth of deterioration in one object.

There is no commission of me’ilah after a commission of me’ilah [has already taken place] with consecrated objects, except [for] an animal and [Temple] service vessels. How so? [If] one rode upon an animal and his fellow came and rode [upon it] and his [other] fellow came and rode [upon it], [or if] one drank from a golden cup and his fellow came and drank [from it] and his [other] fellow came and drank [from it], [or if] one plucked [hair] from a cha- tas and his fellow came and plucked [hair] and his [other] fellow came and plucked [hair], they have all committed me’ilah. Rebbi says: Anything that is not subject to redemption is subject to a commission of me’ilah after a commission of me’ilah.
