JONAH : This story is well known:
JONAH AND THE WHALE (Jonah 1-2): Jonah was
appointed by God to tell the people of Ninevah of their
destruction because of their wickedness. Jonah was afraid and hid
from God on a ship. When a storm occurred, the seamen threw Jonah
overboard to please God, and the seas calmed. Jonah was then
swallowed by a "great fish" (whale) for three days and
then was "vomited" up onto dry land.
Jonah then delivered the message to the people of Ninevah, they
prayed to be saved, and they were saved from destruction (i.e.,
God changed His mind about destroying them). Jonah was angry
about these people being saved, and God illustrated to Jonah that
Gentiles (non-Jews, like the people of Ninevah) can be important
to God.
