For the land that you are about to enter and possess is not like the land of Egypt from which you have come. There the grain you sowed had to be watered by your own labors, like a vegetable garden; but the land you are about to cross into and possess, a land of hills and valleys, soaks up its water from the rains of heaven... If, then, you obey the commandments that I enjoin upon you this day, loving the LORD your God and serving God with all your heart and soul, I will grant the rain for your land in season, the early rain and the late. You shall gather in your new grain and wine and oil — I will also provide grass in the fields for your cattle — and thus you shall eat your fill.
Now when you reap the harvest of your land, you shall not reap to the very corners of your field, nor shall you gather the gleanings of your harvest. Nor shall you glean your vineyard, nor shall you gather the fallen fruit of your vineyard; you shall leave them for the needy and for the stranger.
When you gather the grapes of your vineyard, you shall not go over it again; it shall be for the stranger, for the orphan, and for the widow. You shall remember that you were a slave in the land of Egypt; therefore I am commanding you to do this thing.
Don’t plow with an ox and a donkey harnessed together.
Don't muzzle an ox while it is threshing.
Do not neglect the Levite in your community, for he has no hereditary portion as you have. Every third year you shall bring out the full tithe of your yield that year, but leave it within your settlements. Then the Levite, who has no hereditary portion as you have, and the stranger, and the orphan, and the widow in your settlements shall come and eat their fill, so that Hashem your God may bless all the work of your hands that you do.
You shall not oppress a stranger, for you know the feelings of the stranger having yourselves been strangers in the land of Egypt. Six years you shall sow your land and gather in its yield; but in the seventh year, you shall let it rest and lie fallow. Let the needy among your people eat of it, and what they leave, let the wild beasts eat of it. You shall do the same with your vineyards and olive groves. Six days you shall do your work, but on the seventh day you shall rest; in order that your ox and your donkey may have rest, and that your bondsman, and the stranger, may be refreshed.
At the end of every seven years you will make a release/Shmita. This is the nature of the release: every creditor will release what he loaned his neighbor and his brother as it is declared a release to God.
גָּלוּת בָּאָה לָעוֹלָם עַל עוֹבְדֵי עֲבוֹדָה זָרָה, וְעַל גִלּוּי עֲרָיוֹת, וְעַל שְׁפִיכוּת דָּמִים, וְעַל הַשְׁמָטַת הָאָרֶץ.
Exile comes upon the world on account of idolaters, adulterers, and murderers, and for the failure to observe the Shmita.
