John's Birth, Chapter 1
Zechariah and his wife, Elizabeth, had no children. Luke says, "Elizabeth was not able to conceive."
Initially, I would have said that blaming Elizabeth shows that Luke saw the world through a male-chauvinist lens. Since now I know that the Holy Spirit guided Luke's work, maybe I should give Luke the benefit of the doubt.
Gabriel, who might have been on his way to recite Quran to Muhammad, arrived and told Zechariah that he and Elizabeth would have a son, and they should name the son, John. The text does not say so, but I'm guessing that John becomes John the Baptizer.
Baptize means ritual cleansing. I must have been something that Jews did. An archaeological site, Qumran, near the dead sea has big bath tubs, which might have been used for ritual cleansing.
Six months later, Gabriel, possibly still intending to visit Muhammad some six hundred years later, talked to Mary. He told her that she will have a son, and that she should name him Jesus
When John grew up, he lived in the wilderness.
Luke 1:5-80
