What did Jesus say about the adversary ("Satan"), and his power over us?

"I have given you authority to tread on serpents and scorpions, and over all the power of the enemy"

- Lk 10:19

The context 100% about Satan:

"I saw Satan fall like lightning from heaven"

- Lk 10:18

Who is the adversary ("Satan") though?

Can we use what Jesus said to find out?

He mentioned serpents and scorpions... why?

Do we know anyone in scripture that used these creatures to show their power over us?

“the LORD (YHWH) your God… who led you through the great and terrifying wilderness, with its fiery serpents and scorpions”

- Deut 8:14-15

“Then the LORD (YHWH) sent fiery serpents among the people, and they bit the people, so that many people of Israel died.”

- Numbers 21:6

This is rather chilling to Christians because it's the modern belief/understanding that YHWH is Jesus, but if you really look into what Jesus says, this doesn't seem to be the case.

There is deception at play.

Study the Words of Jesus carefully.
