Mark 11:31 Meaning and Commentary

Mark 11:31

And they reasoned with themselves saying
Privately; perhaps, they withdrew at a little distance for a short time, and consulted among themselves what answer to return; and the amount of their reasonings were this;

if we shall say from heaven, he will say, why then did ye not
believe him?
that is, should they say that John had a divine commission for what he said and did, they were aware that Christ would reply, why did not ye give credit to him? and had you done so, seeing he testified of me, you would have had no occasion to have put the above question; (See Gill on Matthew 21:25).

Mark 11:31 In-Context

29 Jesus said to them, "I'll ask you a question. Answer me, and then I'll tell you why I have the right to do these things.

30 Did John's right to baptize come from heaven or from humans? Answer me!"

31 They discussed this among themselves. They said, "If we say, 'from heaven,' he will ask, 'Then why didn't you believe him?'

32 But if we say, 'from humans,' [then what will happen]?" They were afraid of the people. All the people thought of John as a true prophet.

33 So they answered Jesus, "We don't know." Jesus told them, "Then I won't tell you why I have the right to do these things."
