“Behold, I give unto you power to tread on serpents and scorpions, and over all the power of the enemy: and nothing shall by any means hurt you.”
King James Version (KJV)
10:19 I give you power - That is, I continue it to you: and nothing shall hurt you - Neither the power, nor the subtilty of Satan.
Lu 10:19 To tread on serpents and scorpions. Evidently an allusion to the promise that the seed of woman shall bruise the serpent's head (Ge 3:15). It is a promise of victory over the power of sin, of victory "over all the power of the enemy". The connection shows that it is symbolical.
