One man (o men). "This one," demonstrative pronoun o with men. Hath faith (pisteuei). Like ecei pistin ( Acts 14:9 ). But he that is weak (o de asqenwn). One would expect o de (but that one) in contrast with o men. Ho is demonstrative with de sometimes, but here is probably just the article with asqenwn. Herbs (lacana). From lacanw, to dig. Hence garden herbs or vegetables. Denney feels certain that Paul has in mind a party of vegetarians in Rome.
