Vainity of Power

Ecclesiastes 4:13-16

13  Better is a poor and a wise child than an old and foolish king, who will no more be admonished. 
14  For out of prison he cometh to reign; whereas also he that is born in his kingdom becometh poor. 
15  I considered all the living which walk under the sun, with the second child that shall stand up in his stead. 
16  There is no end of all the people, even of all that have been before them: they also that come after shall not rejoice in him. Surely this also is vanity and vexation of spirit.
