Charles Ellicott Commentary Mark 8:11-12

"And the Pharisees came forth, and began to question with him, seeking of him a sign from heaven, trying him. And he sighed deeply in his spirit, and saith, Why doth this generation seek a sign? verily I say unto you, There shall no sign be given unto this generation." — Mark 8:11-12 (ASV)

And the Pharisees came forth.—See Notes on Matthew 16:1-4. St. Mark, it may be noted, does not mention the presence of the Pharisees, and gives only part of our Lord's answer. On the other hand, he characteristically describes the sighing deeply in spirit in Mark 8:12, which St. Matthew does not give.

There shall no sign be given.—We note the omission of the sign of the prophet Jonas, as given in Matthew 16:4.
