Leviticus 25:2-8

²“Speak to the people of Israel and say to them, 'When you come into the land that I give you, then the land must be made to keep a Sabbath for Yahweh.

³You must plant your field for six years, and for six years you must prune your vineyard and gather the produce.

⁴But in the seventh year, a Sabbath of solemn rest for the land must be observed, a Sabbath for Yahweh. You must not plant your field or prune your vineyard.

⁵You must not conduct an organized harvest of whatever grows by itself, and you must not conduct an organized harvest of whatever grapes grow on your unpruned vines. This will be a year of solemn rest for the land.

⁶Whatever the unworked land grows during the Sabbath year will be food for you. You, your male and female servants, your hired servants and the foreigners who live with you may gather food,

⁷and your livestock and also wild animals may eat whatever the land produces.

⁸You must count off seven Sabbaths of years, that is, seven times seven years, so that there will be seven Sabbaths of years, totaling forty-nine years.
