Expositor's Bible Commentary Commentary Matthew 21:24

"And Jesus answered and said unto them, I also will ask you one question, which if ye tell me, I likewise will tell you by what authority I do these things." — Matthew 21:24 (ASV)

Jesus’ reply is masterly. He responds to their question with a question of his own (v.24), a common enough procedure in rabbinic debate. “John’s baptism” is a way of referring to the Baptist’s entire ministry. Jesus asks whether it was “from heaven, or from men.” Jesus knows that if the religious authorities rightly answer it, they will already have the correct answer to their own question. If they respond, “From heaven,” then they are morally bound to believe John— and John pointed to Jesus ; they will therefore have their answer about Jesus and his authority. If they respond, “From men” (v.26), they offer the wrong answer; but they will not dare utter it for fear of the people.
