Both clauses introduce a topic with ammā and use a prohibitive lā with a jussive verb. The content names two different duties, while the parallel expression lends them corresponding weight.
Three layers matter: the syntax of the topic and prohibition; the appropriateness of the directives; and the measured parallel arrangement. One layer alone is not a full reading.
