Proverbs 6:9 How long wilt thou sleep, O sluggard? when wilt thou arise out of thy sleep?
10 Yet a little sleep, a little slumber, a little folding of the hands to sleep:
11 So shall thy poverty come as one that travelleth, and thy want as an armed man.
A lazy person wants to sleep all the time and could care less if he ever works. They will use every excuse they can to get out of work. They will even say I need time sleep, I do not have time to work. Now for those who think they do not have to work they will wind up with nothing. People, who do not like to work, receive no money. This is just a warning against being lazy and a sleepy head.
Just as a victim is overcome by a robber, so is the lazy man with his devotion to sleep rather than work, is led to poverty.
