Charles Ellicott Commentary John 4:40

"So when the Samaritans came unto him, they besought him to abide with them: and he abode there two days." — John 4:40 (ASV)

When the Samaritans were come.—The next step in their faith is to go to Him and ask Him to remain with them, that they too may learn from Him; and He, a Jew, accepts the hospitality of Samaria, and abides with them for two days.
