Leviticus 26:25-26

25He will send enemy soldiers to kill the people. They have not done what they promised to do. So he will punish them for that. If they go back to their cities, he will send them diseases. The enemy will win the war.

26The people will not have any food. A woman will bake one loaf for ten families. They will weigh it to give one part to each family. When a person eats his piece of bread, he will still be hungry.
