And you know that that's the information that they suppress and devour

from Vinnie Paz (Ft. Block McCloud) – End of Days Lyrics on Rap Genius

Meaning

He is saying that is the information that they destroy and never tell you about.

Information they “consume” and dont want you to know about
Information they take in, (eat a book = read a book…devour? well instead of eating the book they devour it) and do not permit you find out about it
