11 And the Pharisees came foorth, and began to question with him, seeking of him a signe from heauen, tempting him.
12 And he sighed deepely in his spirit, and saith, Why doeth this generation seeke after a signe? Uerely I say vnto you, There shall no signe be giuen vnto this generation.
13 And he left them, & entring into the ship againe, departed to the other side.
Mk 8:11-13
