Leviticus 19:1-10

And the LORD spoke to Moses, saying, “Speak to all the congregation of the children of Israel, and say to them: ‘You shall be holy, for I the LORD your God am holy. ‘Every one of you shall revere his mother and his father, and keep My Sabbaths: I am the LORD your God. ‘Do not turn to idols, nor make for yourselves molded gods: I am the LORD your God. ‘And if you offer a sacrifice of a peace offering to the LORD, you shall offer it of your own free will. It shall be eaten the same day you offer it, and on the next day. And if any remains until the third day, it shall be burned in the fire. And if it is eaten at all on the third day, it is an abomination. It shall not be accepted. Therefore everyone who eats it shall bear his iniquity, because he has profaned the hallowed offering of the LORD; and that person shall be cut off from his people. ‘When you reap the harvest of your land, you shall not wholly reap the corners of your field, nor shall you gather the gleanings of your harvest. And you shall not glean your vineyard, nor shall you gather every grape of your vineyard; you shall leave them for the poor and the stranger: I am the LORD your God.
