Mark 12:24

And Jesus answering said unto them
Which they thought he was not able to do, but would have been silenced at once by them, as many of their antagonists had been:

do ye not therefore err, because ye know not the Scriptures, neither
the power of God?
what is expressed in Matthew affirmatively, is here put by way of interrogation, which, with the Jews, was a more vehement way of affirming; (See Gill on Matthew 22:29).
