Charles Ellicott Commentary Mark 11:21-22

"And Peter calling to remembrance saith unto him, Rabbi, behold, the fig tree which thou cursedst is withered away. And Jesus answering saith unto them, Have faith in God." — Mark 11:21-22 (ASV)

And Peter calling to remembrance.—St. Mark alone names Peter as the speaker. The form of our Lord’s answer, Have faith in God, is also peculiar to him.
