Luke 10:17-20

17 And the seventy returned again with joy, saying, Lord, even the devils are subject unto us through thy name.

18 And he said unto them, I beheld Satan as lightning fall from heaven.

19 Behold, I give unto you power to tread on serpents and scorpions, and over all the power of the enemy: and nothing shall by any means hurt you.

20 Notwithstanding in this rejoice not, that the spirits are subject unto you; but rather rejoice, because your names are written in heaven.
