19:14 Direction is given to fix landmarks in Canaan. It is the will of God that every one should know his own; and that means should be used to hinder the doing and suffering of wrong. This, without doubt, is a moral precept, and still binding. Let every man be content with his own lot, and be just to his neighbours in all things.

De 19:14. The Landmark Is Not to Be Removed.

14. Thou shalt not remove thy neighbour's landmark, which they of old have set in thine inheritance—The state of Palestine in regard to enclosures is very much the same now as it has always been. Though gardens and vineyards are surrounded by dry-stone walls or hedges of prickly pear, the boundaries of arable fields are marked by nothing but by a little trench, a small cairn, or a single erect stone, placed at certain intervals. It is manifest that a dishonest person could easily fill the gutter with earth, or remove these stones a few feet without much risk of detection and so enlarge his own field by a stealthy encroachment on his neighbor's. This law, then, was made to prevent such trespasses.
