The whole multitude of the people were praying outside at the hour of incense.
Although Zechariah had the faith to pray, he did not have the faith to believe the answer to his prayer. As a chastisement for his lack of faith, he became dumb for a period (Luke 1:18-22). God did not, however, withdraw his promise. When Zechariah’s time of service at the temple was over, he returned to his home, and soon Elizabeth became pregnant (Luke 1:23-25).
