"The name of YHVH comes from afar" seems puzzling; YHVH may come from afar, but what does it mean for his name to do so? Rashi, the medieval compiler of rabbinic tradition, writes the following:
the Name of the Lord: His might, which will be for Him as a name, viz., what He will do to Sennacherib.
He does not give a source, but this interpretation is consistent with the context of these verses:
27 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;
28 And His breath is as an overflowing stream, that divideth even unto the neck, to sift the nations with the sieve of destruction; and a bridle that causeth to err shall be in the jaws of the peoples. [...]
30 And the LORD will cause His glorious voice to be heard, and will show the lighting down of His arm, with furious anger, and the flame of a devouring fire, with a bursting of clouds, and a storm of rain, and hailstones. (etc)
"Might" is consistent with anger, devouring fire, sifting the nations with a sieve of destruction, and so forth.
