So when the Samaritans were come unto him, they besought him that he would tarry with them: and he abode there two days.
All Commentaries on John 4:40 Go To John 4
Cyril of Alexandria
AD 444
He explains in simplicity of words what took place: but prepares again another proof, that Israel ought justly to be cast off from their hope, and the aliens to be transplanted into it. For the Jews with their bitter and intolerable surmises, spitefully entreat Jesus manifoldly working miracles and radiant in God-befitting glory, and blush not to rage to so great an extent as to make Him an exile, and zealously to drive out of their city Him Who is the giver to them of all joy: while the Samaritans persuaded by the words of one woman, consider that they ought to come to Him with all speed. And when they were come, they began zealously to entreat Him to come into their city, and to pour forth to them of the word of salvation; and readily does Christ assent to both, knowing that the grace will not be unfruitful. For many believed because of His own Word.
Let him that is God-loving and pious hence know, that from them that grieve Him Christ departeth, but He dwelleth in them that gladden Him through obedience and good faith.
