Zechariah 14:6-7 And it shall come to pass in that day, that the light shall not be clear, nor dark: But it shall be one day which shall be known to the LORD, not day, nor night: but it shall come to pass, that at evening time it shall be light.

Sometimes the LORDs dispensations with the Kirk is such, that they can neither be said to be dark nor clear, neither like night, nor like day; but somewhat of light, and somewhat of darkness in the dispensation; somewhat of judgemental, and somewhat of mercy may be the case of the Kirk.
A second thing we notice of this, That the time of the Kirks trouble thought sometimes the LORD is pleased to lengthen, and to make it long; yet sometimes also, as it is here, it shall be but a short while, and but for one day.
Thirdly, That the Kirks trouble though it be but for a short time, and but for one day, and nobody kens[knows] when it will end: Yet for the comfort of the Kirk it is a day known unto the LORD, though neither enemies nor friends kens when the Day of delivery will come, yet it is a day known to the LORD: it is a limited time that God hath set the bounds of.
Fourthly, That when the Kirk in all appearance and probability, looks like a thicker and blacker darkness and great desolations, then very shortly the LORD will make light to arise, and the Day Spring from on High to arise upon the Kirk, even at the evening, at even -tide it shall be light.
