And the children of Israel did eat manna forty years, until they came to a land inhabited; they did eat manna, until they came unto the border of the land of Canaan.

Let us also see if we are able to find Quadragesima’s mystical number somewhere else in the Scriptures. We read that holy Moses fed the children of Israel with heavenly manna in the desert for the space of forty years. Good is the number, then, which always opens heaven. Good is the number, I say, by which Noah’s righteousness is preserved and the children of Israel are fed. For this reason let us also observe this number so that the heavens might be opened to us in order that the rain of spiritual grace might fall upon us and the manna of the spiritual sacraments refresh us. For, after the fashion of our fathers, by this observance of Quadragesima we are both made righteous and nourished: we are made righteous by the washing [of baptism] and nourished by the sacraments [of bread and wine].
