Barely trustin' niggas, over a decade they been knowin' me
Shit, life at the bottom, nobody but God got em'

from J. Cole – Dollar And A Dream III Lyrics on Rap Genius

Meaning

Despite knowing his friends from his neighborhood for over a decade, Cole doesn’t trust any of them. He only trust in God.

Also a result of the paranoia effects from smoking weed in the line previously. As seen in Welcome

Man, it’s hard to trust friends
When the paranoia blends wit the marijuana
Wonder will this high ever end
Swear I’ll never smoke again

He finds it hard to trust his friends when he’s blazed.
