Luke 10:17-21

And the seventy returned with joy, saying, Lord, even the demons are subject unto us in thy name. And he said unto them, I beheld Satan fallen as lightning from heaven. Behold, I have given you authority to tread upon serpents and scorpions, and over all the power of the enemy: and nothing shall in any wise hurt you. Nevertheless in this rejoice not, that the spirits are subject unto you; but rejoice that your names are written in heaven. In that same hour he rejoiced in the Holy Spirit, and said, I thank thee, O Father, Lord of heaven and earth, that thou didst hide these things from the wise and understanding, and didst reveal them unto babes: yea, Father; for so it was well-pleasing in thy sight.
