ISB ~ John 4 v28

left her water jar:The woman becomes both a believer and a missionary, accepting Jesus as the Messiah and sharing that belief with her hometown (4:39-42).

• Morally (St. Augustine, Tract. on John 15, 16, 30): the water jar is the fallen desire of man that draws pleasure from the dark wells of the world but is never satisfied for long. Conversion to Christ moves us, like the Samaritan woman, to renounce the world, leave behind the desires of our earthen vessels, and follow a new way of life.
