Job 6:7

I sigh when food is put before me, and my groans pour out like water.

“Son of man, eat your bread with trembling, and drink your water with quivering and anxiety.

For I have eaten ashes like bread and mixed my drink with tears

I ate no rich food, no meat or wine entered my mouth, and I did not anoint myself with oil until the three weeks were completed.

Then He told me, “Son of man, I am going to cut off the supply of food in Jerusalem. They will anxiously eat bread rationed by weight, and in despair they will drink water by measure.

But she replied, “As surely as the LORD your God lives, I have no bread—only a handful of flour in a jar and a little oil in a jug. Look, I am gathering a couple of sticks to take home and prepare a meal for myself and my son, so that we may eat it and die.”

and tell them that this is what the king says: ‘Put this man in prison and feed him only bread and water until I return safely.’”

“Ah, Lord GOD,” I said, “I have never defiled myself. From my youth until now I have not eaten anything found dead or mauled by wild beasts. No unclean meat has ever entered my mouth.”
