I was reading somewhere i cant remember.
but Bob Marley and the Wailers original recording of this song is from a live gig in London. and it was apparently originally titled "no woman nuh cry" and anyone who knows better correct me if im wronge. but i believe 'nuh' translates from native jamaican to 'do not' or dont. so if im not mistaken the song would be "No woman, do not cry" which i believe to be a line of comfort for the woman. the song is about the trenchtown living.
