In the well-known biblical account of the prophet Jonah, God instructed His reluctant Israelite servant to deliver a warning to the city of Nineveh, an Assyrian stronghold. Assyria was traditionally a bitter enemy of Israel. Jonah unwisely attempted to shirk his duty and flee from his responsibility. To get away, he booked passage on a ship in Joppa (modern-day Jaffa) going to Tarshish, which some theories connect with an ancient port also called Tartessos in the region of what is now Spain, though other theories abound.
