Mark 8:10–13 (Listen)

10 And immediately he got into the boat with his disciples and went to the district of Dalmanutha.

11 The Pharisees came and began to argue with him, seeking from him a sign from heaven to test him. 12 And he sighed deeply in his spirit and said, “Why does this generation seek a sign? Truly, I say to you, no sign will be given to this generation.” 13 And he left them, got into the boat again, and went to the other side.
