The soul of the sluggard craves and gets nothing, while the soul of the diligent is richly supplied. (Pro 13:4)
“You shall not covet your neighbor’s house; you shall not covet your neighbor’s wife, or his male servant, or his female servant, or his ox, or his donkey, or anything that is your neighbor’s.”(Exo 20:17)
In our Bibles coveting is an interesting concept, but itself it simply sounds like desire. But in the contexts the word appears, it clearly means desire out of proportion and intention to have/take what one cannot have.
At its core, to covet is to entertain the desire to seize upon something which rightly belongs to another. Another way to say it is “to intend to have what belongs to another.” James says that sin, in general, starts with a desire that is then mismanaged. Covetousness can start with a desire to have fruit brought on by seeing a tree covered in tasty but prohibited fruit. And instead of getting fruit one is allowed, one obsesses over the other.
I’ve come to think that of the keys to overcoming covetousness is to become productive. Proverbs 13:4 above implies this (it does not use the Hebrew word for covet, but the idea is similar). The sluggard craves but does not get. James makes this observation about the source of quarrelling: “You desire and do not have, so you murder. You covet and cannot obtain, so you fight and quarrel. You do not have, because you do not ask [in prayer or perhaps of a brother when in genuine need]. (Jas 4:2)” Interestingly, if somebody desires something, even if that desire is spurred on by a neighbor’s goods, it would appear that if you are diligent you soul will be richly supplied insofar as your diligence is for pursuing the good.
The cure for coveting is probably not turning off one’s desire to have a house, a wife, or property in general. Instead, to cure covetousness we should exercise diligence in pursuing and accomplishing good. And, when you do have a need that is not met by diligence or that is too pressing, then ask [God or neighbor].
