After relating details about the birth of John the Baptizer and of Jesus, Luke tells us that John began his ministry in the 15th year of the reign of Tiberius Caesar, that is, in the spring of 29 C.E.
Alguses kirjutab Luukas üksikasjalikult Ristija Johannese ja Jeesuse sünnist ning seejärel annab ta teada, et Johannes alustas oma teenistust keiser Tibeeriuse viieteistkümnendal aastal, see on 29. aasta kevadel.
