Whoso walketh uprightly shall be saved: but he that is perverse in his ways shall fall at once.
He that is perverse in his ways (cf. note, Proverbs 28:6 , 'in two ways') shall fall at once - so as not to rise again. There shall be no need of a second fall (1 Samuel 26:8). Gejer translates, 'shall fall in one of them'-in one of the two ways.
