your harvest, nor gather the grapes of your untended vines" (), and by the supportive verse, "In the Seventh Year you must let it (i.e. the ground) rest and lie fallow, so that the poor among your people may eat from the field and the wild animals may consume what they leave. Do the same with your vineyard and olive grove" (). Grain cannot be harvested by using a sickle, nor can a person reap an entire field, or make use of beasts to separate the grain from the husks by treading. Grapes that are on the vine can be taken, sufficient for ones immediate needs, but they cannot be pressed in a winepress, but only in a small tub. When certain farmers began to secretly sow their fields during the Seventh Year and to harvest what they had planted, and to cover-up their action by saying that such produce was a mere aftergrowth from last year's planting, the Sages of Israel were compelled to enact restrictions on Seventh Year produce and to forbid all aftergrowths () of grain, legumes and those vegetables which are usually planted by mankind, in order to put an end to their deception. Other rabbinic authorities prohibit only the aftergrowths of vegetables, but permit the aftergrowths of legumes and grain. They permitted, however, to pick the fruits of trees that grow of themselves during the Seventh Year, for one's immediate needs, and to gather such vegetables and herbs that are not normally planted by humans, such as wild rue (Ruta chalepensis), either wild asparagus (Asparagus aphyllus) or amaranth (Amaranthus blitum var. silvestre), purslane (Portulaca oleracea), wild coriander (Coriandrum sativum), parsley growing alongside rivers (Apium graveolens), garden rocket growing in marshlands (Eruca sativa), sweet marjoram (Majorana syriaca), white-leaved savory (Micromeria fruticosa), and the like of such things. Had any of these been kept watch over in the courtyard of a house, their aftergrowths would be forbidden to eat in the Seventh Year. Rabbi Nathan ben Abraham permits the gathering of aftergrowths of mustard greens (Sinapsis alba) during the Seventh Year. An ancient practice in the Land of Israel was to permit the gathering of spring onions which grew of themselves during the Seventh Year, after the first rains had fallen upon them and sprouted. The laws governing Aftergrowths apply only to crops grown in the Land of Israel. Heter mechira In the late 19th century, in
