Leviticus 19:1-3 The Lord said to Moses, Speak to the entire assembly of Israel and say to them: ‘Be holy because I, the Lord your God, am holy. Each of you must respect your mother and father, and you must observe my Sabbaths. I am the Lord your God’.
Leviticus 25:8-15 Count off seven sabbath years—seven times seven years—so that the seven sabbath years amount to a period of forty-nine years. Then have the trumpet sounded everywhere on the tenth day of the seventh month; on the Day of Atonement sound the trumpet throughout your land. Consecrate the fiftieth year and proclaim liberty throughout the land to all its inhabitants. It shall be a jubilee for you; each of you is to return to your family property and to your own clan. The fiftieth year shall be a jubilee for you; do not sow and do not reap what grows of itself or harvest the untended vines. For it is a jubilee and is to be holy for you; eat only what is taken directly from the fields. In this Year of Jubilee everyone is to return to their own property. If you sell land to any of your own people or buy land from them, do not take advantage of each other. You are to buy from your own people on the basis of the number of years since the Jubilee. And they are to sell to you on the basis of the number of years left for harvesting crops.
