From BiblePortal Wikipedia
Gordian Knot [1]
A knot by which the yoke was fastened to the beam of the chariot of Gordius ( q. v .), and which no one could untie except the man who was destined to be the conqueror of Asia; Alexander the Great being ambitious to achieve this feat, tried hard to undo it, but failing, cut it with his sword and marched on to conquest.
