I got scriptures in my brain, I could spit at your dame
Straight out the good book, look, niggas is shook

from 50 Cent (Ft. Eminem) – Patiently Waiting Lyrics on Rap Genius

Meaning

The “good book” from which 50 Cent is getting his scriptures is the Bible, from which he proposes to quote from memory to your girl.

Pick-up artists always say that as long as you’re confident, it really doesn’t matter what you say to a girl, but I still imagine it would be awkward to just start reciting Scripture to a girl.

Now these other fools are shook cause 50 be taking all of their women.
