¹ sn Sheol refers here not to hell and hell-fire – a much later concept – but to the innermost parts of the earth, as low down as one could get. The parallel with “the foundations of the mountains” makes this clear (cf. Pss 9:17; 16:10; 139:8; Isa 14:9, 15; Amos 9:2).

² sn The terms “beginning” and “end” form a merism, a figure of speech in which two opposites are contrasted to indicate totality (e.g., Deut 6:7; Ps 139:8; Eccl 3:2-8). The words of a fool are madness from “start to finish.”

¹ tn Heb “Sheol and Abaddon” (שְׁאוֹל וַאֲבַדּוֹן (shÿ’ol va’adon); so ASV, NASB, NRSV; cf. KJV “Hell and destruction”; NAB “the nether world and the abyss.” These terms represent the remote underworld and all the mighty powers that reside there (e.g., Prov 27:20; Job 26:6; Ps 139:8; Amos 9:2; Rev 9:11). The Lord knows everything about this remote region.

¹ tn The noun דּוּמָה (dumah) means “silence,” but here it is a proper name, probably referring to a site in northern Arabia or to the nation of Edom. See BDB 189 s.v. II דּוּמָה. If Dumah was an area in northern Arabia, it would be of interest to the Edomites because of its strategic position on trade routes which they used. See J. N. Oswalt, Isaiah (NICOT), 1:398.
