Mk 16:18, Lk 10:19, Rom 16:20
In the Old Testament the psalmist said that God would cause us to tread on lions and vipers. (Psalms 91:13)
Psalms 91:13 Thou shalt tread upon the lion and adder: the young lion and the dragon shalt thou trample under feet.
We, who believe in Jesus as the Christ, have control over all the power of the enemy. (Mark 16:18, Luke 10:19, Romans 16:20)
Mark 16:18 They shall take up serpents; and if they drink any deadly thing, it shall not hurt them; they shall lay hands on the sick, and they shall recover.
Luke 10:19 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.
Romans 16:20 And the God of peace shall bruise Satan under your feet shortly. The grace of our Lord Jesus Christ be with you. Amen.
