1. According to John 2,20: 8,57 after 46 years of building the temple, in 27 CE Jesus
was about 50. Thus he was born in 24/23 BCE. This corresponds to Luke 2,1ss, Matt 2,1ss and Luke 1, 5, which say that Jesus was born under the rule of the emperor Augustus and during the reign of King Herod the Great.
2. The highly political office which was offered to Jesus was the office of the governor of Galilee in the ministry of Herod Antipas. In 6 CE Jesus took over this office.
At that time he was 30; this was his first public office, Luke 3, 23. 6 CE was the crisis of the sons of Herod the Great. Then, after popular disturbances, Archelaos was banished to Gaul by the emperor.
