Zodiac has 12 signs.
12 tribes of Israel
Altar of 12 stone pillars representing 12 tribes israel.
Joseph and his brothers are 12.
Each leader gave an ox as a gift (Ox is also the face of a cherub, cross referencing the 4 faces of cherubs in Revelation in Ezekiel, 3 are identical, then one says ox and one says cherub, revealing face of the cherub)
Jesus had 12 disciples and gave them all a different name (each one is symbolic then of something)
In revelation the holy city has 12 gates, tree of life has 12 crops of fruit, one per month.
Babylon the great has 12 stars on her crown.
And yes the 'star' that the wisemen were following at Jesus birth. That I suspected to be related to astrology, the 'signs' they spoke of.
And I think some of the excluded books of the bible, such as secrets of enoch, and others found at dead sea scrolls adds more to it. I think it was the secrets of enoch detailing the sun/moon/and stars and their orbits, etc.
