'Able to Deliver' in the Bible

Will ye not know what I did, I and my fathers, to all the peoples of the lands? Being able, were the gods of the nations of the lands able to deliver their land from my hand?

Who from all the gods of these nations that my fathers utterly destroyed, which were able to deliver his people from my hand, that your God shall be able to deliver you from my hand?

And now Hezekiah shall not deceive you, and he shall not stimulate you according to this, and ye shall not believe upon him: for not any God of any nation and kingdom was able to deliver his people out of my hand, and out of the hand of my father: much less shall your God deliver you out of my hand.
