Luke 10:19

19 lo, I give to you the authority to tread upon serpents and scorpions, and on all the power of the enemy, and nothing by any means shall hurt you;

Luke 10:19 Meaning and Commentary

Luke 10:19

Behold, I give you power to tread on serpents and scorpions,
&c.] Which may be literally understood, as in ( Mark 16:18 ) ( Acts 28:3 ) , or figuratively of the devil, and his principalities and powers, and all his emissaries, who, for their craft and cunning, and for their poisonous and hurtful nature and influence, may be compared to serpents and scorpions:

and over all the power of the enemy;
of mankind in general, and of the seed of the woman, Christ and his people in particular, Christ has a power over all his power, his whole posse of devils, even the power of the air, of which he is prince; and he communicated this power to his disciples, even to the seventy: adding,

and nothing shall by any means, hurt you;
not the most hurtful and poisonous animals, nor the most malicious persecutors on earth, nor all the devils in hell: as the former venomous creatures, when took up in their hands, should not hurt, their bodies; so the other, whatever they might be permitted to do with respect to their lives, and outward estate, should never hurt their souls, and the eternal welfare of them; nor even hinder the work of God prospering in their hands.

Luke 10:19 In-Context

17 And the seventy turned back with joy, saying, `Sir, and the demons are being subjected to us in thy name;'
18 and he said to them, `I was beholding the Adversary, as lightning from the heaven having fallen;
19 lo, I give to you the authority to tread upon serpents and scorpions, and on all the power of the enemy, and nothing by any means shall hurt you;
20 but, in this rejoice not, that the spirits are subjected to you, but rejoice rather that your names were written in the heavens.'
21 In that hour was Jesus glad in the Spirit, and said, `I do confess to thee, Father, Lord of the heaven and of the earth, that Thou didst hide these things from wise men and understanding, and didst reveal them to babes; yes, Father, because so it became good pleasure before Thee.
