Better is the poor who walks in his integrity than he who is crooked though he be rich (Proverbs 28:6).
It is better to be honest and poor, full of uprightness and integrity, than it is to be crooked and perverse, but rich. A wicked person cannot really enjoy his riches with a bad conscience as a result of wicked, perverse living. There is nothing wrong with earning money and lots of it, if gained from honest work and investment, but not by sin. It is much better to be poor and have a clear conscience before God and others.
