This poem was composed in the voice of Jonah son of Amittai, the reluctant messenger of God who was called upon to prophesy the Destruction of Nineveh — but God forgave them.
Jonah (Yonah, in Hebrew) means dove; the name Amittai has the word “Truth (emet)” embedded in it.
I imagine Jonah as the “birdman” (either dove or raven?) that survived the Flood. He is full of questions about God’s sense of judgment and mercy; the problem of theodicy haunts him.
