Exodus 23:9-12

‘Do not oppress a foreigner; you yourselves know how it feels to be foreigners, because you were foreigners in Egypt. ‘For six years you are to sow your fields and harvest the crops, but during the seventh year let the land lie unploughed 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.
