¹ tn Heb “dart about in.”

² 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.

¹ tn Hebrew שָׂרָף (saraf, “seraph”) literally means “burning one,” perhaps suggesting that these creatures had a fiery appearance (cf. TEV, CEV “flaming creatures”; NCV “heavenly creatures of fire”). Elsewhere in the OT the word “seraph” refers to poisonous snakes (Num 21:6; Deut 8:15; Isa 14:29; 30:6). Perhaps they were called “burning ones” because of their appearance or the effect of their venomous bites, which would cause a victim to burn up with fever. It is possible that the seraphs seen by Isaiah were at least partially serpentine in appearance. Though it might seem strange for a snake-like creature to have wings, two of the texts where “seraphs” are snakes describe them as “flying” (Isa 14:29; 30:6), perhaps referring to their darting movements. See the note at 14:29.
