For the love of money is a root of all kinds of evil. Some have been led astray from the faith in their greed, and have pierced themselves through with many sorrows.
Paul is not saying that love of money is the only source of evil. Vine points out that "There are other passions which are productive of evil; yet there is no sort of evil which the craving for wealth may not induce" (96). Fairbairn writes, "The sentiment is, that there is no kind of evil to which the love of money may not lead men, when it once fairly takes hold of them" (239).
