Satan / Jesus as a serpent.
Samael is the "Venom of God".

Genesis 3 Satan is a title based on a Hebrew word that we later attached to this snake in Revelation 12:9

Numbers 21, here the Israelites were plagued by fiery serpents after complaining against God & Moses. God instructed Moses to make a bronze serpent and mount it on a pole. Those who looked at the bronze serpent were healed from the serpent bites. We then connect God telling Moses to wrap a snake around a pole to… "And as Moses lifted up the serpent in the wilderness, so must the Son of Man be lifted up.”
— John 3:14
