Exodus 23:10-13

“You shall sow your land six years and harvest its yield, but the seventh year you shall let it rest and lie uncultivated, so that the poor among your people may eat [what the land grows naturally]; whatever they leave the animals of the field may eat. You shall do the same with your vineyard and olive grove. “Six days [each week] you shall do your work, but on the seventh day you shall stop [working] so that your ox and your donkey may settle down and rest, and the son of your female servant, as well as your stranger, may be refreshed. Now concerning everything which I have said to you, be on your guard; do not mention the name of other gods [either in a blessing or in a curse]; do not let such speech be heard [coming] from your mouth.
