|| Matthew 16:1-4
MK8:10 Then right away Jesus boarded the fishing boat with his disciples and went to the region of Dalamutha. MK8:11 And the Pharisees approached to test Jesus, and so they began to question him, seeking some kind of sign from heaven. MK8:12 Now Jesus groaned deeply within himself, and then said: “Why does this generation seek a sign? I tell you this truth: No sign will be given to this generation.” MK8:13 After that Jesus left them and boarded the fishing boat again, departing to the other side.
 Matthew 16:1-4: For details see notes in Nazarene Commentary 2000 on Matthew.
 Dalamutha: Matthew calls it Magadan and some texts use such a word. It is possible it is an unknown Aramaic designation for an area now unknown.
 Groaned deeply within himself: Or, in his spirit.
 No sign will be given to this generation: Matthew adds the matter about the sign of Jonah. It is possible, since Mark writes to Romans that he found it an unnecessary confusion to mention it.
