What was mr. beavers phrophecy how did it represent a danger for the children in The Chronicles of Narnia?

The prophesy Mr. Beaver quoted was, "There is a prophecy that two sons of Adam and daughters of Eve will appear and defeat the white witch and put an end to this 100 year winter." The children were seen as the sons and daughters of the prophecy. The witch of course did not want her rule to be ended, and set out to destroy the children. They are eventually crowned kings and queens of Narnia.
