17 The seventy returned with joy, saying, Lord, even the demons are subject to us in Your name! 18 And He said to them, I saw Satan falling like a lightning [flash] from heaven. 19 Behold! I have given you authority and power to trample upon serpents and scorpions, and [physical and mental strength and ability] over all the power that the enemy [possesses]; and nothing shall in any way harm you. 20 Nevertheless, do not rejoice at this, that the spirits are subject to you, but rejoice that your names are enrolled in heaven.
