just a thing i noticed

I started reading "A Biblical Theology of the Old Testament" awhile ago, but as it's a tad dense, I took a break after the Pentateuch. I've picked it up again and am now reading the chapter on Joshua, Judges, and Ruth. As it's been awhile, I couldn't help looking back at the first chapter and seeing what I underlined at the time.
Glancing at the section on the Ten Commandments, I saw the only two commandments I had underlined anything in were the first and last. Of course I'm going to underline the parts that talk about  "Yahweh's exclusive claims to lordship and worship," but it may be a bit telling that the other one that got attention was covetousness.

"The other commandments inevitably manifest themselves in an outward expression to some degree or other, but covetousness can theoretically exist only in the mind and heart and never betray itself in an external act...It raises the covenant requirements to a higher, more spiritual dimension and properly locates the motive for human action, good or bad, in the volitional side of man. Improper desire is a more 'spiritual' level of theft, adultery, and the like and is forbidden for that reason. 
"Even if covetousness never finds fruition in overt behavior, it is still a serious breach of covenant regulation because the Lord who knows the heart is offended by it. It is an expression of dissatisfaction with one's possessions and with his general lot in life. It violates (if only in spirit) the sanctity of personal property and relationships and tends to disrupt the balanced and equitable jurisdiction assigned by the Sovereign of the kingdom. In effect, covetousness impugns the wisdom and goodness of God by questioning His bestowal of life's blessings in  accord with his omniscient plan."
