Exodus 23:9-11

9“Never oppress foreigners. You know what it’s like to be foreigners because you were foreigners living in Egypt.

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.
