Zechariah 14:6 - Matthew Poole's English Annotations on the Holy Bible

In that day; whilst God is fighting with the enemies of his church, the nations that fought against Jerusalem. The light; good estate, peace, and welfare. Shall not be clear; unmixed good, all light, it will not be so well with the church. Nor dark; not so sad as all darkness, there shall be a temper of both, some peace with some trouble; some prosperity with some adversity; some mercy in midst of judgment to allay the bitterness of judgment, and some judgment with our mercies to allay their sweetness.
