Vayikra 19:7-9

Orthodox Jewish Bible

⁷ And if it be eaten at all on the yom hashelishi, it is piggul (unclean sacrificial flesh); it shall not be accepted.

⁸ Therefore every one that eateth it shall bear his avon, because he hath desecrated as chillul the set-apart- as-kodesh thing of Hashem: and that nefesh shall be cut off from among his people.

⁹ And when ye reap the katzir of your land, thou shalt not wholly reap the corners of thy sadeh, neither shalt thou gather the gleanings of thy katzir.
