I don't got one gun on me
Gotta a sum on me to hire a gun army, get ya spun like laundry

from Jay Z – 30 Something Lyrics on Rap Genius

Meaning

Jay is way too wise to be out in the streets firing off rounds. Rather, he hires men to do his dirty work and the spin (kill) the men he wants like (dirty) laundry. Probably the best word play in the song
