Oldest known Orthodox Icon of Christ written in the Century at Mt Sinai Monastery. My favorite Jesus- cover the right face you have the Jesus of mercy. Cover the left face you have the Jesus of justice. Justice and Mercy but the same Son.
Moses and the Burning Bush, Byzantine Mosaic St Catherine's Monastery, Mt Sinai, Egypt. Built on the site where Moses received the 10 Commandments from God. The altar of the church was built over roots of the burning bush.
