הִנֵּ֤ה שֵׁם־יְהוָה֙ בָּ֣א מִמֶּרְחָ֔ק בֹּעֵ֣ר אַפּ֔וֹ וְכֹ֖בֶד מַשָּׂאָ֑ה שְׂפָתָיו֙ מָ֣לְאוּ זַ֔עַם וּלְשׁוֹנ֖וֹ כְּאֵ֥שׁ אֹכָֽלֶת׃
Behold, the name of the LORD cometh from far, With His anger burning, and in thick uplifting of smoke; His lips are full of indignation, And His tongue is as a devouring fire;

the Name of the Lord His might, which will be for Him as a name, viz., what He will do to Sennacherib.

The name of the Lord, the report of what He has done to the army of Assyria.

comes from long ago (מִמֶּרְחָק, lit. from afar.) To realize what He promised long ago.
