{Although Jesus himself baptized not, but his disciples}
(kaitoige I(8873)ous autos ouk ebaptizen all' hoi math(8874)ai autou).
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 kaitoige (and yet indeed), compound
conjunction (kaitoi in  Ac 14:17  Heb 4:3 ) with intensive
particle ge added. This is the last mention of baptism under
the direction of Jesus till the Great Commission ( Mt 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.
