Leviticus 25:2-7

2“Speak to the Israelites and tell them: When you enter the land I am giving you, the land will observe a Sabbath to the Lord.

3You may sow your field for six years, and you may prune your vineyard and gather its produce for six years.

4But there will be a Sabbath of complete rest for the land in the seventh year, a Sabbath to the Lord: you are not to sow your field or prune your vineyard.

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.
