Zechariah 14:7

one day i.e. an unique day, unlike any other: prorsus singularis. Maurer. Comp. Ezekiel 7:5, and for the idea Jeremiah 30:7.

shall be known to the Lord Rather, is known, R. V. Comp. Mark 13:32. "Quo temporis momento ingruet soli Deo est notum." Maurer.

not day nor night Neither wholly day nor wholly night, but a chequered mixture of both. The new creation shall be ushered in, as the first was, by a day of lurid gloom and "darkness visible," which shall not, however, deepen into night, but brighten at its close into the everlasting dawn. "At evening time there shall be light."
