Zechariah says "Behold, the day of the Lord cometh," The Day of the Lord is the Millennial Day, For I will gather all nations against Jerusalem to battle; and the city shall be taken, and the houses rifled, and the women ravished; and half of the city shall go forth into captivity, and the residue of the people shall not be cut off from the city.
Then shall the Lord go forth, and fight against those nations, as when he fought in the day of battle.
