Luke 2:2 This was the first census that took place while Quirinius was governor of Syria. And everyone went to his won town to register.
I looked up several notes on this verse and they all seem to agree that Quirinius was possibly in office for two terms. First 6-4 BC and then 6-9 AD. This verse is referring to his first term. King Herod, or Herod the Great was king from 37-4 BC. 4 BC seems to be the year.
I see no discrepancy with this point he tried to make. I'll be back later.
Deuteronomy 29:29 The secret things belong to the Lord our God, but the things revealed belong to us and to our children forever.....
