One of the Hebrew prophets of the Restoration (of Jerusalem and the Temple) after the Captivity, and who, it would seem, had returned from Babylon with Zerubbabel and Joshua. Signs of the divine displeasure having appeared on account of the laggard spirit in which the Restoration was prosecuted by the people, this prophet was inspired to lift up his protest and rouse their patriotism, with the result that his appeal took instant effect, for in four years the work was finished and the Temple dedicated to the worship of Jehovah, as of old, in 516 B.C.; his book is a record of the prophecies he delivered in that connection, and the style, though prosaic, is pure and clear.
