'Eternity' in the Bible

But Jehovah Elohim is truth; he is the living God, and the King of eternity. At his wrath the earth trembleth, and the nations cannot abide his indignation.

And {you will let go your hand from your inheritance} that I gave to you, and I will make you serve your enemies in the land that you do not know, for you kindled a fire in my anger, until eternity it will be kindled."

To make their land a horror, [an object of] whistling for eternity. All [who] pass by it will be appalled, and he will shake his head.
