Exodus 23:10-12

10“For six years you may plant crops in your fields and harvest them,

11but in the seventh year you must leave the land unplowed and unused. In that way the poor among your people will have food to eat, and wild animals may eat what the poor people leave. You must do the same with your vineyards and olive groves.

12“For six days you will do your work, but on the seventh day you must not work. Then your ox and donkey can rest. The slaves born in your household and foreigners will also be refreshed.
