Exodus 23:10-13

“For six years you are to sow your fields and harvest the crops, but during the seventh year let the land lie unplowed and unused. Then the poor among your people may get food from it, and the wild animals may eat what is left. Do the same with your vineyard and your olive grove. “Six days do your work, but on the seventh day do not work, so that your ox and your donkey may rest, and so that the slave born in your household and the foreigner living among you may be refreshed. “Be careful to do everything I have said to you. Do not invoke the names of other gods; do not let them be heard on your lips.
