What is Montag trying to do while sitting on the subway? Why are the other passengers afraid of him? See p.118-120.

Montag is reading the Bible. He frightens the other passengers when he stands and repeatedly yells "shut-up", all while speaking gibberish d waving around a book.

"Shut up, shut up, shut up!" It was a plea, a cry so terrible that Montag found himself on his feet, the shocked inhabitants of the loud car staring, moving back from this man with the insane, gorged face, the gibbering, dry mouth, the flapping book in his fist.
