A person who is miserly towards others is sometimes so overwhelmed by this trait that he will prevent other people from giving to the needy. He will do this in order to avoid the embarrassment of not assisting them himself. He thus fulfils what the Sages said in tractate Avos: “One who does not want to give nor that others should give — is a wicked person.”
There are some individuals who are even more miserly to the point that they cannot enjoy their own possessions. About them it is written in Koheles (6:1-2): There is an evil I have observed… a man to whom God has given riches, wealth and honor, and he lacks nothing that the heart could desire, yet God did not give him the power to enjoy it.
