The proverb pictures those who make a way of life out of wickedness. Perhaps they ambush traders who pass through the area, and plunder their goods.
This also has to do with attitude. The attitude of the believer is this, my respect and my regard, the things that I appreciate are the long-term things of life, the stable things of life. It is the unbeliever who is all out for the shifting, unstable things. The things I can have today, no matter what happens tomorrow. This little picture which is almost in every chapter is brought up here in the context of attitude, drawing attention to this. ‘I want’, we have to say, ‘the things that are permanent and rooted, and firm. I do not want to do things that will destroy Christian character, I do not want to do things that will result in no abiding spiritual fruit, trivial things, passing things.’
