Luke 10:17-20

17And the seventy returned with joy, saying, Lord, even the demons are subject to us through thy name.

18And he said to them, I beheld Satan as lightning falling out of heaven.

19Behold, I give you the power of treading upon serpents and scorpions and over all the power of the enemy, and nothing shall in anywise injure you.

20Yet in this rejoice not, that the spirits are subjected to you, but rejoice that your names are written in the heavens.
