Ethiopian priests and monks walk during the annual festival of Timkat in Lalibela, Ethiopia. The festival celebrates the Baptism of Jesus in the Jordan River. During Timkat, the Tabot, a model of the Ark of the Covenant, is taken out of every Ethiopian church for 24 hours and paraded during a procession in towns across the country. Over 80% of Ethiopians are estimated to be Orthodox Christians. Ethiopian Orthodox Christians believe the real Ark of the Covenant (a vessel containing the Ten Commandments) is held in Aksum. It is guarded by a select group of monks, whose sole commitment is to protect the sacred vessel.
