Exodus 23:10-12

10You must plant seed in your fields for six years. Then you can bring your crops home at harvest time.

11But in the seventh year, you must let your fields lie empty. Do not dig them and do not plant anything in them. Then poor people among you can eat the food that they find in your fields. After that, the wild animals can eat any food that still remains. Do the same thing with your vineyards and your fields of olive trees.

12Do your work for six days each week, but do not work on the seventh day. Then your oxen and your donkeys will have time to rest. Any slave who was born in your home and any foreigner who works for you may also have time to rest. That will help them to be strong.
