1 Corinthians 10:12
On all these accounts then let us flee covetousness, the maker of beggars, the destroyer of souls, the friend of hell, the enemy of the kingdom of heaven, the mother of all evils together; and let us despise wealth that we may enjoy wealth, and with wealth may enjoy also the good things laid up for us; unto which may we all attain, etc.
