Hello, I am an ESL, i like learning English Idioms, i think if i can read the whole story which generate the idiom, i will gain a deep understanding of the idiom. So i searched the forum to find useful link upon this.

But what a pity, the forum is too universe to find the source i need. So could any expert guide me some good website which introduce the original stories of the idioms ? i am greatful for your helping.

Here is an example of what i need below:

From Story:
The ant and the dove
An ant went to the bank of a river to quench its thirst, and being carried away by the rush of the stream, was on the point of drowning. A dove sitting on a tree overhanging the water plucked a leaf and let it fall into the stream close to her. The ant climbed onto it and floated in safety to the bank. Shortly afterwards a birdcatcher came and stood under the tree, and laid his lime-twigs for the dove, which sat in the branches. The ant, perceiving his design, stung him in the foot. In pain the birdcatcher threw down the twigs, and the noise made the dove take wing.

One good turn deserves another.
