Saint Caleb was known as Elesbaan and was the sixth century king of Ethiopia when Christians living in the Arabian peninsula were being attacked. Byzantine emperors Justin I and Justinian supported Elesbaan when he led his soldiers in battle to protect the Christians living there.
Later in his life, Elesbaan abdicated his throne, took the name of Caleb, and lived as a hermit. He died while he was living as a monk in Jerusalem, around the year 555.
Saint Caleb, show me how to stand up for those who are being persecuted.
