Six in the fifth place means:
Keeping his jaws still.
The words have order.
A man in a dangerous situation, especially when he is not adequate to it, is inclined to be very free with talk and presumptuous jokes. But injudicious speech easily leads to situations that subsequently give much cause for regret. However, if a man is reserved in speech, his words take ever more definite form, and every occasion for regret vanishes.
