How is a nega examined? A man is examined [in the position of] someone hoeing and of someone picking olives. A woman [is examined in the position of] someone shaping dough, and of someone nursing her child, and of someone who is weaving on a standing loom who exposes her underarm, for her right arm. R’ Yehudah says: Also [she assumes the position] of someone who is spinning linen for her left arm. Just as he is examined for his nega, so is he viewed for his shaving.

A person may examine any negaim except for his own. R’ Meir says: Also not the negaim of his relatives. A person may annul any vows except for his own. R’ Yehudah says: Also not the vows of his wife that are between her and others. A person may examine any first-born [animals] except for his own.
