A.T. Robertson Commentary Mark 11:30

"The baptism of John, was it from heaven, or from men? answer me." — Mark 11:30 (ASV)

Answer me (αποκριθητε μο). This sharp demand for a reply is only in Mark. See also verse 29. Jesus has a right to take this turn because of John's direct relation to himself. It was not a dodge, but a home thrust that cleared the air and defined their attitude both to John and Jesus. They rejected John as they now reject Jesus.
