“And upon this came his disciples, and marvelled that he talked with the woman: yet no man said, What seekest thou? or, Why talkest thou with her?”
John 4:27 — Greek Interlinear
Church Fathers on John 4:27
And upon this came His disciples, and marveled that He talked with the woman. They marveled at the exceeding kindness and humility of Christ, in condescending to converse with a poor woman, and a Samaritan.
He who came to seek that which was lost, sought the lost one. This was what they marveled at: they marveled at His goodness; they did not suspect evil.
The woman is almost turned into an Apostle. So forcible are His words, that she leaves her waterpot to go to the city, and tell her townsmen of them. The woman then left her waterpot, i.e. gave up low bodily cares, for the sake of benefiting others. Let us do the same. Let us leave off caring for things of the body, and impart to others of our own.
