Webster(i)
18 And he said to them, I beheld Satan as lightning fall from heaven.
19 Behold, I give to 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 to you; but rather rejoice, because your names are written in heaven.
