Deu 19:14 | JFB | STEP | 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.

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.
