Book 2 · Section 78

(78) Why was it that Noah lived after the deluge three hundred and fifty years? (#Ge 9:28). It is now declared that in two periods of seven years the form of the world was originally created and now renewed under Noah. But the wise man lives for a period of fourteen quarters of a century; and fourteen times twenty-five is equal to seven times fifty, or fifty times seven. And it is the principle of the seventh year and also of the fiftieth, which has an especial order of its own explained and ordained in Leviticus.
