Mishnah Negaim 13:12: If he enters a synagogue, they make for him a wall ten Tefachim [specific unit of length] high by four Tefachim wide. He enters first and exits last. Anything that is saved by a seal in the tent of a dead person is saved by a seal in a house with a Nega. Whatever is saved by being covered in the tent of a dead person is saved by being covered in a house with a Nega, says Rabbi Meir. Rabbi Yossi says, Anything that is saved by a seal in the tent of a dead person is saved by being covered in a house with a Nega. Whatever is saved by being covered in the tent of a dead person, even if it is uncovered in a house with a Nega, remains pure.

Mishnah Negaim 14:1: How does one purify the leper? He would bring a new earthenware pitcher and place within it a Revi'it [specific unit of volume] of spring water and bring two wild birds. He slaughters one of them over the earthenware vessel and the spring water. He digs and buries it before him. He takes cedar wood, and hyssop and a red string and ties them together with the ends of the string. He surrounds them with the tips of the wings and the tip of the tail of the second one. He dips and sprinkles seven times on the back of the hand of the leper. Some say on his forehead. And so too would he sprinkle on the outer lintel of the house.
