Son of man, eat thy bread with quaking, and drink thy water with trembling and with carefulness; Eat thy bread with quaking - Assume the manner of a person who is every moment afraid of his life, who has nothing but a morsel of bread to eat, and a little water to drink. Thus signifying the siege, and the straits to which they should be reduced. See this explained, Ezekiel 12:19 (note).
