30 “The woman then left her water-pot.” Having heard, “I that speak with you am He,” and having received Christ the Lord into her heart, what could she do but now leave her water-pot, and run to preach the gospel? She cast out lust, and hastened to proclaim the truth. Let them who would preach the gospel learn; let them throw away their water-pot at the well. You remember what I said before of the water-pot: it was a vessel with which the water was drawn, called hydria, from its Greek name, because water is hydor in Greek; just as if it were called aquarium, from the Latin. She threw away her water-pot then, which was no longer of use, but a burden to her, such was her avidity to be satisfied with that water. Throwing her burden away, to make known Christ, “she ran to the city, and says to those men, Come, and see a man that told me all things that ever I did.” Step by step, lest those men should get angry and indignant, and should persecute her. “Is this Christ? Then they went out of the city, and came to Him.”
