▼ The identity of this “club” (also referred to as a “serpent” in the next line) is uncertain. It may refer to an Assyrian king, or to Ahaz. For discussion see J. N. Oswalt, Isaiah (NICOT), 1:331–32. The viper/adder referred to in the second half of the verse is his successor.

▼ Heb “flying burning one.” The designation “burning one” may allude to the serpent’s appearance or the effect of its poisonous bite. (See the note at 6:2.) The qualifier “flying” probably refers to the serpent’s quick, darting movements, though one might propose a homonym here, meaning “biting.” (See J. N. Oswalt, Isaiah [NICOT], 1:332, n. 18.) Some might think in terms of a mythological flying, fire breathing dragon (cf. NAB “a flying saraph”; CEV “a flying fiery dragon”), but this proposal does not make good sense in 30:6, where the phrase “flying burning one” appears again in a list of desert animals.
