Mark 8:9KJV

7And they had a few small fishes: and he blessed, and commanded to set them also before .

8And they that had eaten were about four thousand: and he sent them away.

9And straightway he entered into a ship with his disciples, and came into the parts of Dalmanutha.

10And the Pharisees came forth, and began to question with him, seeking of him a sign from heaven, tempting him.

11And he sighed deeply in his spirit, and saith, Why doth this generation seek after a sign? verily I say unto you, There shall no sign be given unto this generation.
