'Food' in the Bible

Yahweh has sworn by his right hand, and by the arm of his strength, "Surely I will no more give your grain to be food for your enemies; and foreigners shall not drink your new wine, for which you have labored:

The wolf and the lamb shall feed together, and the lion shall eat straw like the ox; and dust shall be the serpent's food. They shall not hurt nor destroy in all my holy mountain," says Yahweh.
