Jeremiah 18:3

The prophet Jeremiah addresses the Jews in these words: "And I went down to the potter's house. Behold, he made a work on the stones. The vessel that he made in his hands was broken. Again he made another vessel, as it pleased him to make it. And the word of the Lord came to me, saying, 'Cannot I do to you as this potter, O house of Israel? Behold, you are like the clay of the potter in my hands.' " For I call your attention to this, that, as I said, after human transgression the great Hand was not content to leave as a trophy of victory its own work, debased by the evil one, who wickedly injured it from motives of envy, but moistened and reduced it to clay, as a potter breaks up a vessel, that by the remodeling of it all the blemishes and bruises in it may disappear, and it may be made afresh faultless and pleasing.

When, therefore, God speaks of an irremediable calamity, he does not say vessels of the potter, but an earthen vessel; when, for instance, he wished to teach the prophet and the Jews that he delivered up the city to an irremediable calamity, he bade him take an earthen wine-vessel, and crush it before all the people, and say, "Thus shall this city be destroyed, be broken in pieces." But when he wishes to hold out good hopes to them, he brings the prophet to a pottery, and does not show him an earthen vessel, but shows him a vessel of clay, which was in the hands of the potter, falling to the ground: and brings him to it saying, "If this potter has taken up and remodelled his vessel which has fallen, shall I not much rather be able to restore you when you have fallen?" It is possible therefore for God not only to restore those who are made of clay, through the laver of regeneration, but to bring back again to their original state, on their careful repentance, those who have received the power of the Spirit, and have lapsed.

Whatever is discerned by the eyes arrives to the judgment and understanding of the soul through every other sense, through hearing, smelling, tasting and touching, but is retained even more so by the mind. Thus, the prophet was commanded to go to the potter's house and there to hear the instructions of the Lord. "When," he says, "I arose and went down to the potter's house, he was making something on the wheel," which the Seventy translated with the ambiguous and misleading word "stones," for abanim and organum, both meaning "potter's wheel," are sometimes called stones, depending on the region and local dialect. "When," he continues, "I discerned that the vessel that he was making out of clay suddenly fell apart," this occurred by the providential agency of God, that the artisan's hand, unwittingly, would create a parable by its mistake. Then the potter who had destroyed his clay vessel on the turning wheel made of it something else, as seemed to him the thing to do. And immediately the Lord said to the prophet, "If this potter has such power that he can remake something out of the same clay that disintegrated, am I not able to do the same for you who seem to have perished?"
