One of the old saints, according to the legend, in his journey overtook two travelers. One was a greedy, avaricious, covetous man; the other was of a jealous and envious nature. When they came to the parting of ways, the saint said he would give them a parting gift. Whichever made a wish first would have his wish fulfilled, and the other man would get a double portion of what the first had asked for.
The greedy man knew what he wanted; but he was afraid to make his wish, because he wanted a double portion and could not bear the thought of his companion getting twice as much as he had. But the envious man was also unwilling to wish first, because he could not stand the idea of his companion getting twice as much as he would get. So each waited for the other to wish first.
At length the greedy man took his fellow by the throat and said he would choke him to death unless he made his wish. At that the envious man said, “Very well; I will make my wish. I wish to be made blind in one eye.” Immediately he lost the sign of his eye – and his companion went blind in both eyes.
