Pure speech. Ps 15:2–3 and 24:4 suggest that proper
speech is a requirement for entrance into the cult. Here the idea seems to be
that the impure speech of idolatry is replaced with pure speech by means of
which one can praise the Lord. Or perhaps we should understand “pure speech” as
the opposite of “unintelligible speech” which prevents communication between
the parties (Isa 33:19; Ezek 3:5, 6). (Adele Berlin, Zephaniah: A
New Translation with Introduction and Commentary [AYB 25A; New Haven: Yale
University Press, 2008], 133)
