38 Then some of the scribes and Pharisees said to him, Teacher, we want you to show us a sign.

39 But Jesus answered them, The people today are bad. They have gone away from God. They want a sign. No sign will be given them but the sign of the prophet Jonah.

40 Jonah was inside the big sea animal for three days and three nights. So the Son of Man will be in the ground for three days and three nights.
