Mark 8:10

8They ate and were filled. They took up seven baskets of broken pieces that were left over.

9Those who had eaten were about four thousand. Then he sent them away.

10Immediately he entered into the boat with his disciples and came into the region of Dalmanutha.

11The Pharisees came out and began to question him, seeking from him a sign from heaven and testing him.

12He sighed deeply in his spirit and said, “Why does this generation seek a sign? Most certainly I tell you, no sign will be given to this generation.”
