Jonah in Easton's Bible Dictionary

a dove, the son of Amittai of Gath-hepher. He was a prophet of Israel, and predicted the restoration of the ancient boundaries (2 Kings 14:25-27) of the kingdom. He exercised his ministry very early in the reign of Jeroboam II., and thus was contemporary with Hosea and Amos; or possibly he preceded them, and consequently may have been the very oldest of all the prophets whose writings we possess. His personal history is mainly to be gathered from the book which bears his name. It is chiefly interesting from the two-fold character in which he appears, (1) as a missionary to heathen Nineveh, and (2) as a type of the "Son of man."
