'Short' in the Bible

And they became very short of food in Samaria; for they kept it shut in till the price of an ass's head was eighty shekels of silver, and a small measure of doves' droppings was five shekels of silver.

But the Rab-shakeh said to them, Is it to your master or to you that my master has sent me to say these words? has he not sent me to the men seated on the wall? for they are the people who will be short of food with you when the town is shut in.
