Leviticus 25:5-7

5You are not to reap what grows by itself from your crop, or harvest the grapes of your untended vines. It is to be a year of complete rest for the land.

6Whatever the land produces during the Sabbath year can be food for you — for yourself, your male or female slave, and the hired worker or alien who resides with you.

7All of its growth may serve as food for your livestock and the wild animals in your land.
