1 Timothy 6:9-10, 17

But those who [are not financially ethical and] crave to get rich [with a compulsive, greedy longing for wealth] fall into temptation and a trap and into many foolish and harmful desires that plunge people into ruin and destruction [leading to personal misery]. For the love of money [that is, the greedy desire for it and the willingness to gain it unethically] is a root of all sorts of evil, and some by longing for it have wandered away from the faith and pierced themselves [through and through] with many sorrows.

As for the rich in this present world, instruct them not to be conceited and arrogant, nor to set their hope on the uncertainty of riches, but on God, who richly and ceaselessly provides us with everything for our enjoyment.
