Is the boy who cried wolf in the Bible?
The Boy Who Cried Wolf is one of Aesop's Fables.
Aesop wrote long-form aphorisms, or "fables" including The Tortoise and the Hare & The Fox and the Sour Grapes.
Aesop lived in the 6th century BCE (about a century before the Jews wrote Genesis, which would become the first book of the Torah). Though many ancient Greek and regional myths and fables were adopted by early Judaism and repeated in various forms in the Tanakh, The Boy Who Cried Wolf is not one of them.
