The LORD shall smite thee with a consumption, and with a fever, and with an inflammation, and with an extreme burning, and with the sword, and with blasting, and with mildew; and they shall pursue thee until thou perish. Consumption - שחפת shachepheth, atrophy through lack of food; from שחף shacaph, to be in want.
Fever - קדחת kaddachath, from קדח kadach, to be kindled, burn, sparkle; a burning inflammatory fever.
Inflammation - דלקת dalleketh, from דלק dalak, to pursue eagerly, to burn after; probably a rapidly consuming cancer.
Extreme burning - חרחר charchur, burning upon burning, scald upon scald; from חר char, to be heated, enraged, etc. This probably refers, not only to excruciating inflammations on the body, but also to the irritation and agony of a mind utterly abandoned by God, and lost to hope. What an accumulation of misery! how formidable! and especially in a land where great heat was prevalent and dreadful.
Sword - War in general, enemies without, and civil broils within. This was remarkably the case in the last siege of Jerusalem.
Blasting - שדפון shiddaphon, probably either the blighting east wind that ruined vegetation, or those awful pestilential winds which suffocate both man and beast wherever they come. These often prevail in different parts of the East, and several examples have already been given. See Genesis 41:6 (note).
Mildew - ירקון yerakon, an exudation of the vegetative juice from different parts of the stalk, by which the maturity and perfection of the plant are utterly prevented. It comes from ירק yarak, to throw out moisture.
Of these seven plagues, the five former were to fall on their bodies, the two latter upon their substance. What a fearful thing it is to fall into the hands of the living God!
