Yet they do not rise above fleshly needs. Hearing of bread that gives life to the world, they still imagine earthly bread. They have their belly as god, as it is written (Phil 3:19).
They are held fast by the vices of the belly, so as justly to hear that "their glory is in their shame" (Phil 3:19).
You will find this speech very similar to the words of the Samaritan woman. Christ our Savior spoke at length with her and taught about spiritual water.
He said clearly: "Everyone who drinks of this water will thirst again, but whoever drinks of the water that I shall give him will never thirst forever. The water that I shall give him will become in him a spring of water flowing into eternal life" (Jn 4:13-14).
But because of the ignorance present in her, she is carried off in another direction. She leaves the spiritual spring and, giving it no thought at all, turns her mind toward the supply of perceptible water.
She says, "Lord, give me this water, that I may not thirst, nor come here to draw" (Jn 4:15). The speech of the Jews is like these words of hers.
As she proves weak by nature, so also, I think, they have nothing manly or youthful, so to speak, in their thinking. They appear effeminate in the unmanly desires of the belly.
They prove the truth of what is written about them: "For the fool will speak foolish things, and his heart will think vain things" (Is 32:6).
