'Ration' in the Bible

When I break off your supply of bread, ten women will bake your bread in one oven; they will ration your bread by weight, and you will eat and not be satisfied.

Then he said to me, "Son of man, I am about to remove the bread supply in Jerusalem. They will eat their bread ration anxiously, and they will drink their water ration in terror

So the king assigned them a daily ration from his royal delicacies and from the wine he himself drank. They were to be trained for the next three years. At the end of that time they were to enter the king's service.
