Leviticus 25:5-7

5Whatever 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.

6And 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,

7even your domestic animals and the [wild] animals that are in your land shall have all its crops to eat.
