When thou reapest thine harvest in thy field, and hast forgot a sheaf in the field, thou shalt not go again to fetch it: it shall be for the stranger, for the fatherless, and for the widow: that the LORD thy God may bless thee in all the work of thine hands.
And thou shalt remember that thou wast a servant in the land of Egypt, and the LORD thy God brought thee out thence by a mighty hand and by a stretched out arm: therefore the LORD thy God commanded thee to keep the sabbath day.
