Adjudication shifts from individual violence to institutional violence. Decisions by civil courts are backed up by the monopoly over violence that is lawfully possessed by the civil government. In order to reduce violence in men's competition for scarce resources, the legal system enforces legal title and voluntary contracts. Vengeance is God's monopoly. He has done this in order to increase social peace.
Legal predictability is a means of increasing social peace.
So is legal title to property. A moral claim to scarce resources may be legitimate in God's eyes. In Old Covenant Israel, the non-owners who were most often singled out by God as deserving of special consideration by owners were widows, orphans, and strangers. Nevertheless, God distinguishes moral claims from legal claims. Under the Mosaic law, God granted very few legal claims to members of these three categories.
