House, wife, qualifications, car, hobbies, income ... in fact ANYTHING

The longer formulations [in 4th (Exodus 20:8-11) and 10th Commandments (Exodus 20:17)] discourage us from trying to find exceptions to the universality of this commandment. 'You shall not covet anything' would not be enough, for our sinful hearts (and the heart is the culprit here) covet in specifics as well as generalities. So God gives us both, and, as with the ninth commandment, focuses on relationships between the believer and his neighbor - the relationships disrupted by coveting.  (p844 DOCTRINE OF THE CHRISTIAN LIFE (Theology of Lordship))
