The constellation Scorpio represents the tribe of Dan.

Most Biblical scholars believe that the Antichrist will come from the tribe of Dan.

They believe this because of the prophecy declared over Dan by his father, Israel declared Dan to be a snake that judges (Genesis 49:16-17). This also may account for the choice to use Scorpio to represent Dan since the Hebrew word for Scorpio is Akrab and it means conflict. 

Further, in the book of Revelation chapter 7 verses 5-8, there is a catalogue of all of the tribes to be sealed in the last days as part of the 144000. Dan is not listed. 

The constellation of Scorpio represents the victory of Jesus because, although it’s first decan constellation is the accursed serpent, the remaining two speak of the strong one who holds him.
