Isaiah 30:27

the name of the Lord appears here to be synonymous with what is elsewhere called the "glory of Jehovah" (cf. the parallelism, ch. Isaiah 59:19; Psalms 102:15) i.e. the visible manifestation of His presence. It may have the same sense in ch. Isaiah 18:7, the Temple of the future being conceived as the scene of a perpetual Theophany (Ezekiel 43:2 ff.). Amongst the later Jews the expression "the Name" was commonly used, out of reverence, to avoid the use of Jehovah (cf. Leviticus 24:11).

cometh from far In Judges 5:4; Deuteronomy 33:2, the Theophany comes from Seir or Sinai; here its origin is left indefinite. Jehovah's coming is like that of the thundercloud which appears on the distant horizon, no eye having observed the mysterious process by which it was formed. In what follows the figure of the storm is inseparably blended with an anthropomorphic representation of Jehovah.

and the burdenthereof is heavy Render: and with thick uplifting (of smoke) (Cheyne). R.V. "in thick rising smoke." Cf. Judges 20:38.

full of indignation Perhaps "full of angry foam."
