Midrash sobre Ester 5:11

There is wealth that is beneficial to its possessor and wealth that is harmful to him. An example of wealth that was harmful to its possessor was the wealth of Korah, as it is said: So they, and all that appertained to them, went down alive into the pit (Num. 16:33). Haman’s riches were also harmful to him, for though it is said: And Haman recounted unto them the glory of his riches (Est. 5:11), ultimately: So they hanged Haman (ibid. 7:10). An example of wealth that was beneficial to its owner was that of Jehoshaphat: Now Jehoshaphat had riches and honor in abundance (II Chron. 18:1). What happened to him? Then Jehoshaphat cried out, and the Lord helped him (ibid., v. 31).
