Moreover the light of the moon shall be as the light of the sun, and the light of the sun shall be sevenfold, as the light of seven days, in the day that the LORD bindeth up the breach of his people, and healeth the stroke of their wound. Behold, the name of the LORD cometh from far, burning with his anger, and the burden thereof is heavy: his lips are full of indignation, and his tongue as a devouring fire: And his breath, as an overflowing stream, shall reach to the midst of the neck, to sift the nations with the sieve of vanity: and there shall be a bridle in the jaws of the people, causing them to err. Ye shall have a song, as in the night when a holy solemnity is kept; and gladness of heart, as when one goeth with a pipe to come into the mountain of the LORD, to the mighty One of Israel. And the LORD shall cause his glorious voice to be heard, and shall shew the lighting down of his arm, with the indignation of his anger, and with the flame of a devouring fire, with scattering, and tempest, and hailstones. For through the voice of the LORD shall the Assyrian be beaten down, which smote with a rod. And in every place where the grounded staff shall pass, which the LORD shall lay upon him, it shall be with tabrets and harps: and in battles of shaking will he fight with it. For Tophet is ordained of old; yea, for the king it is prepared; he hath made it deep and large: the pile thereof is fire and much wood; the breath of the LORD, like a stream of brimstone, doth kindle it.
The intensified light must be understood as symbolic of glory and righteousness. The godless nations would be sifted in a sieve of destruction. Assyria would be beaten down by the Lord, and every stroke of punishment would be accompanied by jubilant music from Judah. The burning fires of Topheth, which represent hell, are ready to welcome the wicked king.
