Preaching the Gospel, Preparing a People
The Bible is clear on when the birth took place, except for one piece of missing information.
That is when Zechariah was serving as Cohen at the temple. It is there that he learned his wife will be with child. A feat that would not be accomplished until he left the temple in July. Then, the Bible tells us Mary announced she was with child when Zechariah’s wife was in the six month. Count the months on your fingers and you come up with the birth six months after John was born in March. The birth took place during the feast of sukkot.
