Covetous men are fools, miserable wretches, buzzards, madmen, who live by themselves, in perpetual slavery, fear, suspicion, sorrow, discontent, with more of gall than honey in their enjoyments; who are rather possessed by their money than possessors of it.
If money be not thy servant, it will be thy master. The covetous man cannot so properly be said to possess wealth, as that it may be said to possess him.
There is not a vice which more effectually contracts and deadens the feelings, which more completely makes a man's affections centre in himself, and excludes all others from partaking in them, than the desire of accumulating possessions. When the desire has once gotten hold on the heart, it shuts out all other considerations, but such as may promote its views. In its zeal for the attainment of its end, it is not delicate in the choice of means. As it closes the heart, so also it clouds the understanding. It cannot discern between right and wrong; it takes evil for good, and good for evil; it calls darkness light, and light darkness. Beware, then, of the beginning of covetousness, for you know not where it will end.
Desire leads to coveting, and coveting leads to stealing. For if the owner (of the coveted object) does not wish to sell, even though he is offered a good price and is entreated to accept, the person (who covets the object) will come to steal it, as it is written (Mikha 2:2) [Micah 2:2], 'They covet fields and (then) steal them.' And if the owner approaches him with a view to reclaiming his money or preventing the theft, then he will come to murder. Go and learn from the example of Achav [Ahab] and Navot [Naboth].
