The water source in the church is very ancient. It is mentioned in the early Byzantine era. The source itself is in the mountain, and it enters the church through a seventeen-meter tunnel. From ancient times, this spring-fed the entire Nazareth settlement with water. Women approached him to draw water, and near him, archangel Gabriel announced the blessed news to the Virgin Mary. For this reason, the church is also called the church of the Archangel Gabriel.
