Before that it is permissible to make a light meal thereof even without tithing, but not after. Now, if the stage of liability was reached, so that it became tebel, and it was resown, the produce is not tebel but hullin, and one may enjoy a light meal thereof before tithing. As for the second tithe, the Rabbis did not enact that its produce shall be second tithe too, as in the case of terumah, because there was no fear that the Israelite would keep and resow it, in order to evade his obligations, since the second tithe might be redeemed and eaten outside palestine, v. Ter. IX. 4. ');"><sup>9</sup></span>
