Mark 8:12

12 With a sigh that came straight from his heart, he said, "Why does this generation want a sign? Yes! I tell you, no sign will be given to this generation!"

Mark 8:12 Meaning and Commentary

Mark 8:12

And he sighed deeply in his Spirit
In his human soul; and which shows that he had one, and was subject to grief and sorrow, and all passions and infirmities, excepting sin. This deep sigh was on account of the hardness of their hearts, the malignity of their minds, and insincerity of their intentions; who had no view to come at truth by this inquiry, but to ensnare him:

and saith, why doth this generation seek after a sign?
when so many have been shown among them, and they will not believe:

verily I say unto you, there shall no sign be given to this
generation:
such as they desired; namely, one from heaven. The Evangelist Matthew adds, "but the sign of the Prophet Jonas"; (See Gill on Matthew 16:4), (See Gill on Matthew 12:40).

Mark 8:12 In-Context

10 After sending them away, Yeshua got into the boat with his talmidim and went off to the district of Dalmanuta.

11 The P'rushim came and began arguing with him; they wanted him to give them a sign from Heaven, because they were out to trap him.

12 With a sigh that came straight from his heart, he said, "Why does this generation want a sign? Yes! I tell you, no sign will be given to this generation!"

13 With that, he left them, got into the boat again and went off to the other side of the lake.

14 Now the talmidim had forgotten to bring bread and had with them in the boat only one loaf.
