'Lack' in the Bible

Therefore My people will go into exilebecause they lack knowledge;her dignitaries are starving,and her masses are parched with thirst.

“Can a woman forget her nursing child,or lack compassion for the child of her womb?Even if these forget,yet I will not forget you.

Why was no one there when I came?Why was there no one to answer when I called?Is My hand too short to redeem?Or do I have no power to deliver?Look, I dry up the sea by My rebuke;I turn the rivers into a wilderness;their fish rot because of lack of waterand die of thirst.
