Perry's Index to the Aesopica
Fables exist in many versions; here is one version in English:
THE TWO FROGS AT THE WELL
There were two frogs whose pond had dried up, so they went looking for a new
place to live. When they came to a well, one of them thought that they should
jump in immediately, but the other one said, 'Wait: what if the water were to
dry up here too; how would we be able to get back out again?'
The story teaches us not to approach a situation without thinking about
it carefully first.

in the Aesopic fable tradition. Invaluable.
