Job 24:2

Some remove the land-marks -Landmarks are pillars or stones set up to mark the boundaries of a farm. To remove them, by carrying them on to the land of another, was an act of dishonesty and robbery - since it was only by marks that the extent of a man’s property could be known. Fences were uncommon; the art of surveying was not well understood, and deeds describing land were probably unknown also, and their whole dependence, therefore, was on the stones that were erected to mark the boundaries of a lot or farm. As it was not difficult to remove them, it became a matter of special importance to guard against it, and to make it a crime of magnitude.
