But how?/ how can it be?/ how is it possible?
A question expressing wonder or surprise about the possibility or manner in which something can happen or exist.
("Sometimes you disappear (from the loss you have found) and sometimes you disappear. Is it like hunting? A priest and he is in a house of burial, an old man and it is not according to his honor" - Sanhedrin 18:2, and so: "Like hunting, you cause a family to be troubled... Is it like hunting, she leaves golden vessels, young men, and chooses bronze vessels" - J. Burla/ Silver, 114, and so on: "Petro sat down and was astonished. He was like a hunted man, a great and wealthy man" - Agnon/ City and its Fullness, 611).
