What does 2 Samuel 23:7 mean?

But if you mess with people like that, it's like grabbing a thorn bush with your bare hands. You can't touch them without getting hurt, so you have to handle them with tools, and in the end, you just burn them up where they lie. 2 Samuel 23:7 - Modern Text Bible

(David is talking about people who are dangerous and destructive, comparing them to thorn bushes that can't be handled safely. The only way to deal with them is to keep your distance and get rid of them completely.)
