Charles Ellicott Commentary Mark 11:18

"And the chief priests and the scribes heard it, and sought how they might destroy him: for they feared him, for all the multitude was astonished at his teaching." — Mark 11:18 (ASV)

They feared him.—Peculiar to St. Mark. Note also his omission of the facts recorded by St. Matthew:

1. The healing of the blind and the lame in the Temple;
2. The children crying Hosanna.
