Son of Amittai from Gath Hepher (in the Galilee region). He was a patriot. In 2 Kings 14:25, he prophesied the expansion of Israel's borders under King Jeroboam II. He was a "Nationalist Prophet."
He lived under the shadow of the rising Assyrian Empire (Nineveh). The Assyrians were brutal terrorists known for skinning captives alive. Jonah had every reason—politically and emotionally—to hate them.
He was formed by Exclusive Theology. He believed Yahweh belonged to Israel. The idea of offering repentance to Nineveh was offensive to his core identity.
