You shall not remove your neighbor's landmark, which the men of old time have set, in your inheritance which you shall inherit in the land that the LORD your God gives you to possess it.
All Commentaries on Deuteronomy 19:14 Go To Deuteronomy 19
Ambrose of Milan
But on the contrary, if your eye has looked upon a woman to covet her, you have opened a wound, you have driven a weapon into your body. Your very members become tools of sin. If you look upon the property of orphans and drive them from the dwellings of their fathers, you are changing the landmarks that your forefathers set. Your members are tools of iniquity. And so the passions are the author of guilt and not the flesh, for the flesh is the servant of the will. .
