Jesus, Adam, and Rosh Hashana
Second, September 23 is significant because "by some calculations (see Jack Finegan, Handbook of Biblical Chronology), Jesus was born on or very near the 1st day of the 7th month–based on the chronology given in the book of Luke. The calculations are complex but have to do with the time in which Zechariah, father of John the Baptizer, served in the Temple (Luke 1:8), as the “section” of priests in which he was part went on duty at a specific time of year. From that window calculations can be made as to the birth of John, followed by the birth of Jesus six months later."
Wouldn't it be interesting, in the providence of the One who orchestrates redemption and history, if there is a calendar connection between the first Adam and Last Adam, and between the anticipation of atonement and the One who is THE Atonement?
