The first words of this chapter plainly refer to the close of the foregoing chapter, where every thing looked black and melancholy: Behold, trouble, and darkness, and dimness—very bad, yet not so bad but that to the upright there shall arise light in the darkness (Ps. cxii. 4) and at evening time it shall be light, Zech. xiv. 7. Nevertheless it shall not be such dimness (either not such for kind or not such for degree) as sometimes there has been. Note, In the worst of times God's people have a nevertheless to comfort themselves with, something to allay and balance their troubles; they are persecuted, but not forsaken (2 Cor. iv. 9), sorrowful yet always rejoicing, 2 Cor. vi. 10. And it is matter of comfort to us, when things are at the darkest, that he who forms the light and creates the darkness (ch. xlv. 7) has appointed to both their bounds and set the one over against the other, Gen. iv. 4. He can say, "Hitherto the dimness shall go, so long it shall last, and no further, no longer."
