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. Accordingly, it was forbidden in the strictest manner in the law of Moses. “Cursed be he that removeth his neighbor’s land-mark;” Deuteronomy 27:17; compare Deuteronomy 19:14; Proverbs 22:28; Proverbs 23:10.
And feed thereof - Margin, “or, them.” The margin is correct. The meaning is, that they drive off the flocks of others, and “pasture” them; that is, they are at no pains to conceal what they do, but mingle them with their own herds, and feed them as if they were their own. If they drove them away to kill, and removed them wholly from view, it would be less shameful than to keep and claim them as their own, and to make the robbery so public.
