Jesus is the Sun ☀️.

Malachi 4:2
“shall the Sun of righteousness arise with healing in his wings..."

The Sun is the healing through the Chrism activation (Christ).

The Snake and the Pole are the representation of movement of the Sun around going around the center pole of earth, in a Sine Wave formation.
Another write up on this here.

More Biblical evidence:
(Thanks to @kathymooneyham for bringing the verse to my attention)

Numbers 21:8-9

“8 And the LORD said unto Moses, Make thee a fiery serpent, and set it upon a pole: and it shall come to pass, that every one that is bitten, when he looketh upon it, shall live.

Wow! Again...
Fiery serpent is the sun moving up and down while moving around, making a sine wave which looks like a snake. The pole is the sun moving around the center of the earth (North Pole). And within the movement of the fiery snake there is Healing...

This is your 12 Signs (standard of care. Rod of Asclepius). See this video if you haven't yet.

9 And Moses made a serpent of brass, and put it upon a pole, and it came to pass, that if a serpent had bitten any man, when he beheld the serpent of brass, he lived.”

The Rod of Asclepius is used to depict this healing TO THIS DAY. (They stole it and tried to use the representation for evil but it is NOT EVIL! It is even Biblical!)

It is the Sun moving in a Sine Wave around the center pole of earth.

Keystone to the universe.
