Let darkness and the shadow of death stain it; let a cloud dwell upon it; let the blackness of the day terrify it. Let darkness and the shadow of death stain it - יגאלהו yigaluhu, "pollute or avenge it," from גאל gaal, to vindicate, avenge, etc.; hence גאל goel, the nearest of kin, whose right it was to redeem an inheritance, and avenge the death of his relative by slaying the murderer. Let this day be pursued, overtaken, and destroyed. Let natural darkness, the total privation of the solar light, rendered still more intense by death's shadow projected over it, seize on and destroy this day, εκλαβοι αυτην, Septuagint; alluding, perhaps, says Mr. Parkhurst, to the avenger of blood seizing the offender.
Let a cloud dwell upon it - Let the dymme cloude fall upon it - Coverdale. Let the thickest clouds have there their dwelling-place - let that be the period of time on which they shall constantly rest, and never be dispersed. This seems to be the import of the original, תשכן עליו אננה tishcan alaiv ananah. Let it be the place in which clouds shall be continually gathered together, so as to be the storehouse of the densest vapors, still in the act of being increasingly condensed.
Let the blackness of the day terrify it - And let it be lapped in with sorrowe. - Coverdale. This is very expressive: lap signifies to fold up, or envelope any particular thing with fold upon fold, so as to cover it everywhere and secure it in all points. Leaving out the semicolon, we had better translate the whole clause thus: "Let the thickest cloud have its dwelling-place upon it, and let the bitterness of a day fill it with terror." A day similar to that, says the Targum, in which Jeremiah was distressed for the destruction of the house of the sanctuary; or like that in which Jonah was cast into the sea of Tarsis; such a day as that on which some great or national misfortune has happened: probably in allusion to that in which the darkness that might be felt enveloped the whole land of Egypt, and the night in which the destroying angel slew all the first-born in the land.
