"Take heed and beware of covetousness, for one's life does not consist in the abundance of the things he possesses." (Luke 12:15)

There's an old legend about two very covetous men who were granted a wish upon the condition that whoever made the first wish, the second would receive a double portion of what the first requested. The first greedy man would not make his wish because he wanted the double portion for himself. The second covetous man felt the same; thus, he was also unwilling to make the first wish. After a long while, the first, who was strongest of the two, grabbed the second by the throat and said he would choke him to death if he didn't make his wish. As the second man was about to die, he said, "I wish to be made blind in one eye." Immediately, he lost the sight of one eye, and his companion went blind in both eyes!

The moral of this old story is, "Beware of covetousness."
