What is paradoxical about the two books of the Bible that Montag remembers in Fahrenheit 451?

Montag remembers passages he read in his Bible from Ecclesiastes 3:1, "To everything there is a season," and Revelations 22:2, "And on either side of the river was there a tree of life...and the leaves of the tree were for the healing of the nations." The apocalypse Montag has witnessed has clear connections to the apocalypse foreseen in the Bible.
