“Mary set out and traveled to the hill country in haste to a town of Judah, where she entered the house of Zechariah and greeted Elizabeth.”
Why? Why did Mary go to Elizabeth? Elizabeth lived with her husband, the priest Zechariah in Ein Karem, about 5 miles from Jerusalem. That was close enough for the priest, Zechariah, to work in the Temple in Jerusalem when it was his turn for duty. Ein Karem was about 90 miles from Nazareth. That was perhaps a four-day trip for Mary.
