1 Timothy 6:6-8 (KJV) 6:9-10 (YLT)
But godliness with contentment is great gain. For we brought nothing into this world, and it is certain we can carry nothing out. And having food and raiment let us be therewith content.  and those wishing to be rich, do fall into temptation and a snare, and many desires, foolish and hurtful, that sink men into ruin and destruction, for a root of all the evils is the love of money, which certain longing for did go astray from the faith, and themselves did pierce through with many sorrows;
1 Cor 6:9-10 (KJV)
Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind, Nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners, shall inherit the kingdom of God.
Luke 12:15 (KJV)
And he said unto them, Take heed, and beware of covetousness: for a man's life consisteth not in the abundance of the things which he possesseth.
Proverbs 23:4-5 (KJV)
Labour not to be rich: cease from thine own wisdom. Wilt thou set thine eyes upon that which is not? for riches certainly make themselves wings; they fly away as an eagle toward heaven.
