45:4 by thy name. The Persian emperor Cyrus was thus named by God about 150 years before he was born, and about 100 years before Nebuchadnezzar destroyed Jerusalem and the temple, carrying the people of Judah into captivity in Babylonia. The Persian empire still later conquered Babylon, and eventually Cyrus became emperor and fulfilled Isaiah’s prophecy (Ezra 1:1-4) about 175 years after Isaiah pronounced it.
