Zechariah was a post-captivity prophet, and contemporary with Haggai. They both prophesied in the second year of Darius, that is to say, in the days of the second of the four world-empires foretold in Scripture.
Zechariah is chiefly noted for the number of short and instructive visions—eight in all—closing with Daniel 6, and the constant and characteristic use of the expression —In that day—referring to the final judgments of the Lord, culminating in the overthrow of Israel's enemies, the purification of His people, and the introduction of the Millennial reign of Christ.
