John Chrysostom
In gold mines, one experienced in the work does not neglect even the smallest vein, because it may yield great wealth. So also in the divine Scriptures it is not without harm to omit even one stroke or iota. Everything must be examined. Everything in them was spoken by the Holy Spirit, and nothing is superfluous. Notice here too what the Evangelist says: “This was the second miracle Jesus did when He had come from Judea into Galilee.” He did not add “second” in vain. He further magnifies the wondrous conduct of the Samaritans, showing that the inhabitants of Galilee, even after the second sign which they saw, did not reach the height of those Samaritans who had seen nothing.
