Hebrew 13:5 is one simple verse, but the argument is amazing. Readers of Scripture know that the love of money is dangerous (Matthew 6:24; Luke 16:13; 1 Timothy 3:3; 1 Timothy 6:10; 2 Timothy 3:2), but here the writer of Hebrews gives us more.
The two commands in verses 5a and 5b have an important connection. Both of the commands are positive: "keep your life free from love of money" and "be content with what you have." We can see that the "love of money" stands parallel to "what you have." So then, the commands for freedom and contentment are somehow concerned with our possessions.
