Phil, it’s from Macbeth and is Macbeth’s own line in Act 3 Scene 4:
Then comes my fit again: I had else been perfect,
Whole as the marble, founded as the rock,
As broad and general as the casing air:
But now I am cabin’d, cribb’d, confined, bound in
To saucy doubts and fears. But Banquo’s safe?
and is said just before the entry of Banquo’s ghost.
Yes, I would like to see Netanyahu ‘cabin’d’ and see the ghosts of all those he has had killed.
