Caduceus

The picture shown is a caduceus.  I was talking to my mom the other day and she told me that in Bible study they had talked about it in relation to the stick Moses had in the dessert for the Israelites to be healed.  Numbers 21

⁴ And they journeyed from mount Hor by the way of the Red sea, to compass the land of Edom: and the soul of the people was much discouraged because of the way.
⁵ And the people spake against God, and against Moses, Wherefore have ye brought us up out of Egypt to die in the wilderness? for there is no bread, neither is there any water; and our soul loatheth this light bread.
⁶ And the Lord sent fiery serpents among the people, and they bit the people; and much people of Israel died.
⁷ Therefore the people came to Moses, and said, We have sinned, for we have spoken against the Lord, and against thee; pray unto the Lord, that he take away the serpents from us. And Moses prayed for the people.
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.
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.

Mom said that she had always heard that the use of the caduceus as the medical emblem was because of this story in the Bible.  But her Bible Study teacher had said that he was reading something that claimed this was not true about the use of the caduceus.  I told her that the use of the caduceus for a medical emblem was because of the Bible passage but the medical profession is trying to divorce itself form God and the Bible and trying to be more about science.  Mom asked if I could find a reference for her and it ended up being pretty easy.  I went to Wikipedia and looked up caduceus it says that the picture above is the staff that Hermes (Greek god) or Mercury (Roman god) would carry.  Deeper in the article there are two lines that say that this

“The caduceus is often used incorrectly as a symbol of healthcare organizations and medical practice (especially in North America), due to confusion with the traditional medical symbol, the rod of Asclepius, although this has only one snake and is never depicted with wings.”

Therefore, I went on and looked up the rod of Asclepius as seen below.

The short story is that Asclepius is the Greek god of healing and one of his temples is where Hippocrates lived and the rod was associated with the temple and with Hippocrates.  Now what is very interesting is at the end of the article it gives three other possible sources of the staff.  The very last one is it actually the verse and in Numbers. 

Therefore, you can see that they are trying to play down any connections to the Bible and push their agenda of no God and no Bible in modern life.
