Leviticus 25:7-11

Even your cattle and the animals that are in your land shall have all its produce to eat.

‘You are also to count off seven Sabbaths of years for yourself, seven times seven years, so that you have the time of the seven Sabbaths of years, that is, forty-nine years.

You shall then sound a ram’s horn abroad on the tenth day of the seventh month; on the Day of Atonement you shall sound a horn all through your land.

So you shall consecrate the fiftieth year and proclaim a release throughout the land to all its inhabitants. It shall be a jubilee for you, and each of you shall return to his own property, and each of you shall return to his family.

You shall have the fiftieth year as a jubilee; you shall not sow, nor harvest its aftergrowth, nor gather grapes from its untrimmed vines.
