[If] one takes payment for judging, his decisions are void; for testifying, his testimonies are void; for sprinkling or for mixing [purification water] —- his water is [like] cave water, and his ashes are [like] ordinary ashes. If he was a Kohen, and he contaminated him from [eating] his terumah, he may give him to eat, to drink and to anoint himself. If he was an old man, he may give him a donkey upon which to ride. And he may give him his pay like a laborer.
