Years ago I heard a tail,
of three great kings brought to fight hell.
Asked each he did, what threat they posed,
the first he mocked, the second disposed.
The third at last he asked again,
“what weapon have ye to end my reign?”
“Truth” quoth the third, as Hell shrunk back.
The others bowed, their voices cracked.
No greater weapon in life exists,
the light of Truth, every lie evicts.
