If the Decalogue devotes its final commandment to prohibiting desire for whatever belongs to the neighbor, it is because it lucidly recognizes in that desire the key to the violence prohibited in the four commandments that precede it. If we ceased to desire the goods of our neighbor, we would never commit murder or adultery or theft or false witness. If we respected the tenth commandment, the four commandments that precede it would be superfluous.
