There are different situations in which the prohibition against me'ilah applies. There are some articles from which a person benefits that are not ordinarily damageable, e.g., one who uses a pure golden utensil. There are other articles that are damageable, e.g., garments, and utensils made from silver, copper, iron, and the like. When a person derives a p'rutah's worth of benefit from a consecrated substance that is not attached to the ground, if he benefits from an article that is not ordinarily damageable, e.g., he used a consecrated golden utensil, he violates the prohibition against me'ilah. If he benefits from an article that is damageable, e.g., he wore consecrated garments or chopped with a consecrated axe, he does not violate the prohibition against me'ilah until he causes a p'rutah's worth of damage to consecrated property, i.e., the article from which he benefited itself, with the intent to benefit from it even though it causes damage at that time. If he derived a half a p'rutah of benefit and damaged a half a p'rutah or he derived a p'rutah of benefit and damaged a p'rutah's worth of another article, but did not benefit from what he damaged or did not damage the article from which he benefited, he does not violate the prohibition against me'ilah unless he derives a p'rutah's worth of benefit and causes a p'rutah's worth of damage to that article while deriving benefit from it. What is implied? A person removed a patch from a consecrated garment and sewed it unto his garment and wore it, deriving a p'rutah's worth of benefit and causing a p'rutah's worth of damage to the garment from which he removed it, without damaging the patch at all. He does not violate the prohibition against me'ilah, because he derived benefit from one article and damaged another. We already explained, that when a person derives benefit and causes a colleague to derive benefit, the two can be combined to reach the minimum measure of a p'rutah's worth even if there is a long interval between them.
