Zacharias is a biblical figure mentioned in the New Testament, specifically in the Gospel of Luke. He is known as the father of John the Baptist and a priest in the Temple of Jerusalem. Zacharias received a divine message from the angel Gabriel announcing that he and his wife, Elizabeth, would have a son despite their old age. Zacharias initially doubted this message, leading to his temporary muteness until the birth of John. His story highlights themes of faith and divine intervention, as well as the significance of John the Baptist in preparing the way for Jesus Christ.
