If Nachash is serpent in the Garden then it must be Serpent here as well. You have the untenable claim that Scripture taught that the Serpent would be lifted up, it was on one of the flag carriers shaped like a "T"
Numbers 21:4-9 4They traveled from Mount Hor along the route to the Red Sea, to go around Edom. But the people grew impatient on the way; 5they spoke against God and against Moses, and said, "Why have you brought us up out of Egypt to die in the wilderness? There is no bread! There is no water! And we detest this miserable food!" 6Then the LORD sent venomous snakes among them; they bit the people and many Israelites died. 7The people came to Moses and said, "We sinned when we spoke against the LORD and against you. Pray that the LORD will take the snakes away from us." So Moses prayed for the people. 8The LORD said to Moses, "Make a snake and put it up on a pole; anyone who is bitten can
look at it and live." 9So Moses made a bronze snake and put it up on a pole. Then when anyone was bitten by a snake and looked
at the bronze
snake, they lived.
