Isaiah 10:18

New English Translation

¹⁸The splendor of his forest and his orchard
will be completely destroyed,^[a]
as when a sick man’s life ebbs away.^[b]

Isaiah 10:18 tn Heb “from breath to flesh it will destroy.” The expression “from breath to flesh” refers to the two basic components of a person, the immaterial (life’s breath) and the material (flesh). Here the phrase is used idiomatically to indicate totality.
Isaiah 10:18 tn The precise meaning of this line is uncertain. מָסַס (masas), which is used elsewhere of substances dissolving or melting, may here mean “waste away” or “despair.” נָסַס (nasas), which appears only here, may mean “be sick” or “stagger, despair.” See BDB 651 s.v. I נָסַס and HALOT 703 s.v. I נסס. One might translate the line literally, “like the wasting away of one who is sick” (cf. NRSV “as when an invalid wastes away”).
