The Ten Commandments begin with God and end with neighbor. That is intentional. When you have been brought out of the land of Egypt, that not only sets you right with Yahweh your God; it ends up putting things right between you and your neighbor as well. This final commandment sums up the rest by addressing the thoughts and motivations of the heart. In forbidding covetousness, it requires contentment with your own lot, joy in your neighbor's good, and satisfaction with your God and His law.
