The verse centers on "heard", "words", "prophecy", "azarias", "oded", "prophet", "took", and "courage". It is saying that the verse draws attention to "heard" and "words", so its meaning should be read from those terms before moving to application.

A plain takeaway is to answer the verse's own emphasis on "heard" and "words" with trust shaped by these words, not by a vague optimism outside the passage.
