St. John Chrysostom
“Continually He reminds them of the manna, showing the difference, (between it and His bread,) and guiding them to the faith; for if He was able to support their life for forty years without harvest, or grain, or other things in course; much more now will He be able to do so, as having come for greater ends.”
