Writers and poets often make words and actions their topic, I among their number, and this poem also devoted to the subject. Two stanzas of five lines each, with a rhyme scheme of ABABA, makes for an interesting arrangement. (You already know I love chiastic structures.) The unstressed feet vary between the two stanzas, and the second uses enjambment, furthering the contrast between the irony of the first and the plain declaration of the second.
The last line alludes to James 1.26-27. James, Proverbs, Jesus, Paul, all have much to say about the use of the tongue. Peter talks about how ignorance is not silent — on the contrary, and the first stanza alludes to this fact. "For it is God's will that by doing right you should silence the ignorant talk of foolish people" 1Pt 2.15 ISV.
