John 4:1

“When therefore our Lord knew, etc.] Or Jesus, as some copies, as the Vulgate Latin, Syriac, Arabic, and Persic versions read; who is Lord of all, Lord of lords, the one and only Lord of saints: and who knew all things as God; every man, and what is in man; who would believe in him, and who not, and who would betray him; he knew his adversaries, what they thought, said, or did; what was told them, and how it operated in them; and what were the secret motions of their hearts, and their most private counsels and designs; for this is not merely to be understood of his knowledge as man, which he might have by private intelligence from others; though what is here said, might be true also in this…”

More disciples than John -…”

“The Lord knew - Though none informed him of it. John 4:3”

“4:1-42 At a historic well in Samaria, Jesus offered himself as living water. Jesus engaged and confronted people with the revelation of God, and they either followed or fell away. • The Samaritan woman contrasted with Nicodemus at every turn: a woman (not a man), a Samaritan (not a Jew), a sinner (not righteous), and an outcast (not one of Israel’s rabbis). While Nicodemus fell silent and never responded to Jesus’ challenges (3:1-21), this woman acknowledged Jesus as Lord, remained in the light, and exhibited signs of discipleship (see 1:35-51).”
