Perry's Index to the Aesopica
Fables exist in many versions; here is one version in English:
HERACLES AND THE DRIVER
An ox-driver was bringing his wagon from town and it fell into a steep ditch.
The man should have pitched in and helped, but instead he stood there and did
nothing, praying to Heracles, who was the only one of the gods whom he really
honoured and revered. The god appeared to the man and said, 'Grab hold of the
wheels and goad the oxen: pray to the gods only when you're making some effort
on your own behalf; otherwise, your prayers are wasted!'
