The Bible addresses money directly in several passages:
1 Timothy 6:10 (KJV)
10 For the love of money is the root of all evil: which while some coveted after, they have erred from the faith, and pierced themselves through with many sorrows.
Matthew 6:19-24 (KJV)
19 Lay not up for yourselves treasures upon earth, where moth and rust doth corrupt, and where thieves break through and steal: 20 But lay up for yourselves treasures in heaven, where neither moth nor rust doth corrupt, and where thieves do not break through nor steal: 21 For where your treasure is, there will your heart be also. 24 No man can serve two masters: for either he will hate the one, and love the other; or else he will hold to the one, and despise the other. Ye cannot serve God and mammon.
Proverbs 3:9-10 (KJV)
9 Honour the LORD with thy substance, and with the firstfruits of all thine increase: 10 So shall thy barns be filled with plenty, and thy presses shall burst out with new wine.
Hebrews 13:5 (KJV)
5 Let your conversation be without covetousness; and be content with such things as ye have: for he hath said, I will never leave thee, nor forsake thee.
