Deuteronomy 19

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.

Deuteronomy 19:15 . TWO WITNESSES REQUIRED.

15. One witness shall not rise up against a man for any iniquity--The following rules to regulate the admission of testimony in public courts are founded on the principles of natural justice. A single witness shall not be admitted to the condemnation of an accused person.

Deuteronomy 19:16-21 . PUNISHMENT OF A FALSE WITNESS.

16-21. But if convicted of perjury, it will be sufficient for his own condemnation, and his punishment shall be exactly the same as would have overtaken the object of his malignant prosecution. see also Leviticus 24:20 ).
