Jonah or Jonas is a prophet in the Hebrew Bible hailing from Gath-hepher in the Northern Kingdom of Israel around the 8th century BCE. He is the central figure of the Book of Jonah, which details his reluctance in delivering the judgment of Yahweh to the city of Nineveh in the Neo-Assyrian Empire. After he is swallowed by a large sea creature and then released, he returns to the divine mission.

Tarshish occurs in the Hebrew Bible with several uncertain meanings, most frequently as a place far across the sea from Phoenicia and the Land of Israel. Tarshish was said to have exported vast quantities of important metals to Phoenicia and Israel. The same place name occurs in the Akkadian inscriptions of Assyrian king Esarhaddon and also on the Phoenician inscription of the Nora Stone in Sardinia; its precise location was never commonly known, and was eventually lost in antiquity. Legends grew up around it over time so that its identity has been the subject of scholarly research and commentary for more than two thousand years.
