A.T. Robertson Commentary John 4:2

"(although Jesus himself baptized not, but his disciples)," — John 4:2 (ASV)

Although Jesus himself baptized not, but his disciples (καιτοιγε Ιησους αυτος ουκ εβαπτιζεν αλλ' ο μαθητα αυτου). Parenthetical explanation that applies also to 3:22. Imperfect tense means that it was not the habit of Jesus. This is the only N.T. instance of καιτοιγε (and yet indeed), compound conjunction (καιτο in Ac 14:17; Hebrews 4:3) with intensive particle γε added. This is the last mention of baptism under the direction of Jesus till the Great Commission (Matthew 28:19). It is possible that Jesus stopped the baptizing because of the excitement and the issue raised about his Messianic claims till after his resurrection when he enjoined it upon his disciples as a rite of public enlistment in his service.
