quaking

Son of man, eat thy bread with quaking, and drink thy water with trembling and with carefulness;

And I Daniel alone saw the vision: for the men that were with me saw not the vision; but a great quaking fell upon them, so that they fled to hide themselves.

And He said to him, "Where is thy brother?" To which he answered and said, "I know not." Then the Creator said to him, "Be trembling and quaking."
