He was among those who returned to Jerusalem from the Babylonian captivity, following the decree of Cyrus in 538 BC. With the Prophet Haggai (December 16) he began to prophesy in Jerusalem in 520, to encourage the Jews to return to their task of rebuilding the Temple, which they had given up in discouragement. His prophetic ministry is described both in the Book of Ezra and in the Old Testament book that bears his name. His prophecies, in addition to speaking to the situation in which he lived, are replete with prophecies of the coming, and second coming, of Christ. His name means "The Lord is renowned." Sozomen's Ecclesiastical History reports that under the Emperor Honorius, Zacharias' holy relics were discovered by divine revelation in Palestine, and were found to be incorrupt.
