Catena Aurea on John 4:1–6: Augustine of Hippo

At the sixth hour then our Lord comes to the well. The black abyss of the well, methinks, represents the lowest parts of this universe, i. e. the earth, to which Jesus came at the sixth hour, that is, in the sixth age of mankind, the old age, as it were, of the old man, which we are bidden to put off, (Col. 3:9.) that we may put on the new. For so do we reckon the different ages of man’s life: the first age is infancy, the second childhood, the third boyhood, the fourth youth, the fifth manhood, the sixth old age. Again, the sixth hour, being the middle of the day, the time at which the sun begins to descend, signifies that we, who are called by Christ, are to check our pleasure in visible things, that by the love of things invisible refreshing the inner man, we may be restored to the inward light which never fails. By His sitting is signified His humility, or perhaps His magisterial character; teachers being accustomed to sit.
