The book is a revelation to God's people of His sovereign power and loving care for all His creatures, even cattle. This revelation came first to Jonah personally and then through him to the Jews. It was not a revelation to the Ninevites. Their responsibility was simply to repent and humble themselves. This revelation should have moved the Israelites to respond as the Assyrians did namely with repentance and humility. They faced similar threats first from the Assyrians and then from the Babylonians. Jonah's lack of concern for the Ninevites contrasts with God's concern for them that was to be the pattern for His people.
