sn 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.

tn 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.
