The literary term used in the last three lines of the passage is "apostrophe." Apostrophe is a figure of speech where the speaker addresses someone or something that is absent or cannot respond. In this case, the speaker is addressing the verities (truths) and asking them to be their oracles, before realizing they should stop speaking ("But hush no more").
The word "prophecies" could correctly replace "oracles" in the reading passage.
