The Sabbath year (Ex 23:10-23:13)

“For six years you shall sow you land and gather in its yield.  But the seventh year you shall let it rest and be fallow, so that the poor of your people may eat.  What they leave, the wild animals may eat.  You shall do the same with your vineyard and with your olive orchard.  Six days you shall do your work, but on the seventh day you shall rest.  Thus your ox and your donkey may have relief.  Your house born slaves and the resident aliens may be refreshed.  Be attentive to all that I have said to you.  Do not invoke the names of other gods.  Do not let them be heard on your lips.”

For six years you work hard, but on the seventh year you let the land rest.  The Sabbath belongs to the land also. The poor and animals can go free in the fields on the seventh year.  If you have a vineyard or olive orchard, the same applies.  You work for six days and rest on the seventh.  This way the oxen and donkeys get rest.  Your slaves and the resident aliens can also be refreshed.
