A fourth-year vineyard is marked with clumps of earth; and orlah with clay; and graves with lime [that] he mixes [with water] and pours. Rabban Shimon ben Gamliel said: When are these things said? During the Shemittah [lit., seventh] year. However the discreet ones place down the coins and say: “Whatever will have been picked from this [vineyard] shall be deconsecrated on these coins.”
