Leviticus 25:1-7

The LORD spoke to Moses at Mount Sinai, saying, “Speak to the children of Israel and say to them, ‘When you come into the land which I am giving you, then the land shall keep a Sabbath to the LORD. For six years you shall sow your field, and for six years you shall prune your vineyard and gather in its crop. But in the seventh year there shall be a Sabbath of rest for the land, a Sabbath to the LORD; you shall not sow [seed in] your field nor prune your vineyard. Whatever reseeds itself (uncultivated) in your harvest you shall not reap, nor shall you gather the grapes from your uncultivated vine, it shall be a year of sabbatical rest for the land. And all of you shall have for food whatever the [untilled] land produces during its Sabbath year; yourself, and your male and female slaves, your hired servant, and the foreigners who reside among you, even your domestic animals and the [wild] animals that are in your land shall have all its crops to eat.
