'Ancient' in the Bible

The great Dragon, the ancient serpent, he who is called 'the Devil' and 'the Adversary' and leads the whole earth astray, was hurled down: he was hurled down to the earth, and his angels were hurled down with him.

He laid hold of the Dragon--the ancient serpent--who is the Devil and the Adversary, and bound him for a thousand years, and hurled him into the bottomless pit.
