Luke 3 Bible study: What then must we do?

Luke opens with a reign, a governor, three tetrarchs and a high priesthood, each as the WEB names them: "Now in the fifteenth year of the reign of Tiberius Caesar, Pontius Pilate being governor of Judea, and Herod being tetrarch of Galilee, and his brother Philip tetrarch of the region of Ituraea and Trachonitis, and Lysanias tetrarch of Abilene" (3:1), "during the high priesthood of Annas and Caiaphas" (3:2). Then he says where the word of God came: "the word of God came to John, the son of Zacharias, in the wilderness" (3:2) (tap word). Here is what almost everyone misses: Luke's first chapter left John there. It ended, "The child was growing and becoming strong in spirit, and was in the desert until the day of his public appearance to Israel" (1:80), and Luke's next chapter doesn't name him. The desert of 1:80 and the wilderness of 3:2 are the same Greek word (tap wilderness). His father had been told, "you shall call his name John" (1:13), and Luke names him here as "John, the son of Zacharias" (3:2). Then Luke gives words "written in the book of the words of Isaiah the prophet" (3:4), from "The voice of one crying in the wilderness" (3:4) to "All flesh will see God’s salvation" (3:6). Favor's Isaiah 40 draws its line from Isaiah 40:3 to these verses, and this chapter points there and draws no second line. Luke says no more of the men named in 3:1-2 than those two verses say, and these notes don't either.

Genesis 5:1→leads toLuke 3:38

Luke traces Jesus' family back through this chapter's names: “the son of Noah, the son of Lamech, the son of Methuselah, the son of Enoch, the son of Jared, the son of Mahalaleel, the son of Cainan, the son of Enos, the son of Seth, the son of Adam, the son of God” (Luke 3:36-38). Luke spells some names differently (Enos for Enosh, Cainan for Kenan).

Strong's: "(subjectively) compunction (for guilt, including reformation)", and "from G3340", the verb of repent. Thayer: "a change of mind". John came "preaching the baptism of repentance for remission of sins" (3:3), and told the multitudes, "Therefore produce fruits worthy of repentance" (3:8). These are the first two of five times Luke's Greek has the noun (counted in RP2018, the Greek text the WEB translates). The last is in Jesus's words near the end of the book: "that repentance and remission of sins should be preached in his name to all the nations" (24:47).
